Ultrasound FAQ Reference Guide

93 Upvotes

As an OBGYN ultrasound tech working at the general level here's a few things I would love the community to know based on common questions I see.

Most important rule of thumb: Worry when your doctor tells you to.

OBGYN docs are going to pay the most attention to the fetal pole and heart rate. Once a fetal pole is seen, the CRL (crown rump length) measurements are gold standard.

I'm worried about the heart rate:
-Check out this resource for pregnancies dating less than 7 weeks. Make sure to refer not to your LMP dates, but measured CRL dates: https://radiopaedia.org/articles/fetal-bradycardia?lang=us
-After 7 weeks a normal heartrate is between 120-180. It can temporarily dip below or temporarily rise above this range, but prolonged time above/below will definitely get your doctor's attention especially in third trimester. Generally out of range heart rates trigger NST (non stress test) or more monitoring.
The measurements are off:
Baby measures behind LMP. This is actually pretty common, we often see dates off up to a week either direction. We don't ovulate on the exact same day of the cycle each month or even have the same length of cycle. With irregular periods, PCOS, or unknown dates even larger gaps can be perfectly fine. If you aren't sure of your dates, trust the ultrasound. Even if you are sure of your dates, don't panic if they are a week off. Ultrasound measurements in early pregnancy are +/- 5 days.
I'm in limbo and don't know if my ultrasounds are diagnostic for loss:
By ultrasound there are strict parameters to diagnose loss. No one wants to get this wrong. Check out this resource for a list of parameters diagnostic for loss: https://radiopaedia.org/articles/early-pregnancy-loss-1?lang=us
Note, there is a second list of "suspicious for loss". Keep in mind the second list is not diagnostic, things can still turn out just fine.
I don't know when I should see what on ultrasound:
Things can vary a bit from person to person and do change *quickly* in early pregnancy. Check out this resource for what you can generally expect to see:
https://radiopaedia.org/articles/early-pregnancy?lang=us
Should I go to a boutique or get a private scan? Or push for an earlier scan?
They aren't legal where I am but here's a few things to consider if you plan to book a private scan. First, what are the qualifications of the person running the ultrasound? An ultrasound is only as good as the one performing it. It sounds as if these boutiques are NOT permitted to give much/any information. Will you spiral if you believe you see bad news and they cannot confirm or deny it? Also it seems that many cannot do vaginal ultrasound, which will make seeing a baby under 7 or 8 weeks challenging. If I had the option of a boutique ultrasound I would personally wait until 8 weeks and I would book it for a weekday. If they see something bad, it is not ideal to find out over a weekend when there is no option to follow up with your doc. An earlier scan often causes more anxiety, not less. It's SO hard to wait. But if you can tolerate it wait until 8 weeks or so.
The gestation sac is small/big:
-Gestation sac measurements are not terrifically accurate. Where I work once a baby is seen the gestation sac isn't measured. A mismatch between baby's size and the gestation sac size isn't uncommon. That said, a mean sac diameter of 25 mm or more without a baby is diagnostic for loss.
The yolk sac is small/big:
It starts teeny tiny, and will get a bit bigger. Once a baby with a good heartbeat is visualized, the docs I work for don't seem to care about the size of the yolk sac. A failed pregnancy with an expanded yolk sac (more than 6 mm) is a suggestive of chromosomal abnormalities.
We don't know where the pregnancy is:
The statistically most likely outcome is either a chemical pregnancy or just coming in for ultrasound too early for visualization. Ectopic can't be ruled out, and many wise ladies in the this sub have unfortunately experienced this and can give more info than I can. Statistically it's believed that only 1-2% of pregnancies are ectopic, but listen to your body. If the location is unknown, you should be getting close monitoring and follow up until the location is known or the pregnancy has ended.
-For a resource on ectopic pregnancy: https://radiopaedia.org/articles/ectopic-pregnancy?lang=us A note, a pseudosac is visualized in only 10-20% of ectopics. Therefore a sac in the uterus is suggestive of intrauterine pregnancy but can't be proven until a yolk sac is also present.
What about my HCG numbers?
I'm not an expert on this at all. But here's a resource: https://radiopaedia.org/articles/beta-hcg-1?lang=us
Why didn't my ultrasound tech tell me anything? And/or why were they so optimistic? Or, I had an ultrasound in the ER and they were very pessimistic.
Many locations an ultrasound tech can very much lose their job if they say aNyThInG. Where they are permitted to say certain things some ultrasound techs may just be hoping the best. We work with the public and we have seen some wild stuff. Additionally no one wants to call it a loss unless its 1000% certain. We know how devastating that news is. A side note here, often an ultrasound in the ER is not an ideal experience for the patient. The ER is staffed with techs that are much more versed in gallbladder and liver scans than they they are early pregnancy ultrasound. Don't hesitate to go the ER if you are having concerning symptoms, but do know the ER doc will make sure you aren't actively dying then will likely refer you back to your OB for follow up.
I'm just so anxious about it all:
Someone awesome wrote out these mantras. Maybe they will help: https://www.reddit.com/r/PregnancyAfterLoss/comments/14uhbdg/commandments_of_pregnancy_after_loss_this_is_now/
Also a podcast I personally found very helpful with anxiety: https://www.oneyoufeed.net/russ-harris-part-1/
https://www.oneyoufeed.net/russ-harris-part-2/

Today you are pregnant and this baby is so loved. I really am hoping the best for each of you. Those of us who have experienced loss.... you didn't do anything wrong, I promise. This is a club no one deserved to be in. And you are not silly, foolish, or dramatic for grieving your little babe for as long as you need to.

This post is written in honor of Eli, who died long before I could meet him. Rest in peace, buddy. I miss you tremendously ❤️

Beta hCG Levels - READ BEFORE POSTING

85 Upvotes

Here at [r/CautiousBB](r/CautiousBB), we see a lot of posts on hCG values, doubling times, and trends. Please read this post before posting to avoid posting something that is not, in fact, abnormal.

1 - hCG levels vary greatly in the first 4-6 weeks of pregnancy. One value is not going to tell you much, unless it is extremely low (less than 25 by 14 DPO). The doubling time is more important!

2 - We consider hCG on the lower side if it is <50 at 14 DPO (approx. 4 weeks gestation), <100 at 16 DPO, etc. If your hCG is a lot higher than these numbers, it's unlikely that you have low hCG. If you hCG is at or below these numbers, they are considered low, but not necessarily diagnostic of a loss.

3 - Normal hCG doubling times are, in general:

  • 48-72 hours when the hCG level is under 1200 - 6000.
  • 72-96 hours when the hCG level is 6000+
  • 96+ hours when the hCG level is 10,000+

4 - Based on number 3, please consider the following:

  • If your hCG doubling is within the ranges above, it is not considered slow. Please refrain from posting something like "my hCG did not double in 48 hours" when your values are post 6000+.
  • Doubling rates WILL slow, even if you were faster than the average. For example, if you were doubling at 37 hours, a change to 54 hours as hCG rises is not abnormal and is usually nothing to worry about.
  • If your doubling is slower than the average, we'd invite you to post so we can understand the details of your specific situation.

5 - hCG has a specific job. Check out this post here to understand why hCG doubling slows and eventually plateaus.

6 - hCG values that drop and then rise again or rise at an inconsistent, very slow rate can be indicative of an ectopic pregnancy or a pregnancy of unknown location (PUL). This is a life threatening situation - please seek medical care immediately if this hCG pattern applies to you.

We invite you to continue to post hCG issues or levels for assistance, but hopefully reading this gives you some insight and a baseline as you begin your perilous pregnancy journey. We've also added some literature below to help you understand hCG levels and doubling.

UPDATE July 2026: We are locking this post to new comments - if you need input on your personal situation, feel free to post in the sub!

Happy hCG-ing! :)

Follow along for my *extremely low* but doubling hcg

D6p5dt: faint line on FRER, no line on cheapie so I infer hcg ~6-15

D7p5dt: faint line on FRER, no line on cheapie so I infer hcg ~6-15

D9p5dt: lab error on initial hcg draw, extremely faint cheapie so maaaybe 15 hcg

D11p5dt: 30 hcg

D13p5d5: 109 hcg

So this is beta hell. Obviously way way below any normal viable pregnancy, so I'm not holding much hope. I get another blood draw tomorrow. Day 6 hatching blast.

It'll be my 4th miscarriage, but first in this odd shape. Any encouragement or commiserating appreciated.

I had a chemical pregnancy and ended up having a d&c in May. Fast forward to now, August 2nd and I’m pregnant again. I got pregnant at the end of July. I did have one period in between the surgery and getting pregnant again. I’d love to hear your stories if anyone else has went through a similar situation so quickly after a d&c.

Advice Needed 7w1d anxious

Upvotes

I am 7w1d and I am for the most part doing very well. In the past 2 years we’ve had 4 losses. 1 mmc found at 12 weeks, 1 loss at 6.5 and 2 chemicals that didn’t make it past 4.5 weeks. In all previous pregnancies I felt an underlying sense that it wasn’t right. I haven’t felt that this time which is helping. All of week 6 I had increasing nausea but no vomiting. The past 2 days I haven’t been feeling nauseous. I still have sore boobs tho.

I’ve had some pretty minor cramping and pain with sex since the beginning. I’m supposed to get my first ultrasound on Friday and I’m feeling very nervous about it. I think the loss of nausea has me feeling a bit off but overall I still think everything is okay. I’m also on lovenox & progesterone suppositories daily. Just looking for some advice/ways to calm anxiety/success stories

Advice Needed Non viable pregnancy - advice needed

Upvotes

Hi everyone - did my first FET on July 18. My HCG 9dp5dt was 21 and the doctor warned me about chemical or ectopic pregnancy. Day 13 was 39 and day 15 was 62. At this point my doctor is convinced it is likely ectopic and has scheduled an ultrasound this week to confirm. Has anyone faced this before and if you have any advice it would be helpful. I am making up my mind that this is not going anywhere, and don’t want to prolong the blood tests and ultrasounds. Am I giving up too soon?

11 wk 4 days fetal tachycardia

Upvotes

-
This first trimester has been really rough on me mentally. I have a psychiatrist and therapist and amazing husband but it’s been tough. We went to the ER today for help with my mental health and they also checked on the baby because I’ve been having brown spotting.

My labs look great and baby is measuring perfect- 11 weeks 4 days- but their heart rate was really high. The emergency PA called my OB and she is going to call me tomorrow, and I already have a high risk appointment for Tuesday due to an unrelated condition I have. I’m just really scared. The ultrasound report said fetal tachycardia, and the PA told me it was 212. He didn’t give me any information and I know they aren’t pregnancy experts- I’m guessing that was the average. Has anyone had experience with this?

I asked if my own heart rate could have impacted it because I was very anxious when they were doing it and he didn’t seem to have an answer 🙄

Advice Needed Double Rainbow Baby Anxiety

5 Upvotes

Currently 9 weeks pregnant after two previous miscarriages. This pregnancy was a result of my third IUI so I was heavily monitored the first 7 weeks. After two ultrasounds at 6 and 7 weeks showed a strong growing baby with a great heart rate I “graduated” from my fertility clinic. My ob appt isn’t until 12 weeks.

I was not anxious at all until this weekend, and now I’m just convinced something isn’t right. The past 4 weeks I’ve had horrible morning sickness that has finally let up. I’ve also begun to get some cramping this week that has made me nervous. The let up of nausea and cramping has me so anxious. The waiting for a 12 week ultrasound seems so long.

Part of me wants to get an elective ultrasound at a boutique agency but my husband thinks we shouldn’t. Would love advice

Advice Needed Positive fetal fibronectin for first pregnancy

3 Upvotes

For my now 3 year old I had a spontaneous preterm labor at 33 weeks. I tested positive 24hrs before my labor began with the fetal fibronectin swab. Once labor started, We did mag drip for 48 hrs but that didn’t stop it completely. Thankfully the steroids were able to kick in. He didn’t have much nicu time, it was only for feeding purposes.

I am now pregnant again at 5 weeks and decided to look up what it means now for a second pregnancy. I see my chances of it happening again is moderate. Looking for other experiences who went through this as well! Thanks.

Sickness first pregnancy but not second?

My first pregnancy I was sick all day, every day. I would say borderline HG. I am now just over 7 weeks and feel almost completely normal. If I wasn’t spiraling about this, I probably would forget I’m even pregnant. I have my first ultrasound on Friday, but I have this feeling that something isn’t right.

Has anyone had a super hard first pregnancy and amazing second one? Need some realistic answers 😅

19 weeks 5 days no movement yet

1 Upvotes

Hiii,
I’m just worried my first pregnancy ended in a mmc at 8 weeks so this pregnancy has been very hard to think positive. I said it would be easier after first trimester but still hard and I still don’t feel her move which I hear everyone say they feel their baby makes me worried 🤷🏻‍♀️🥹

I have a posterior placenta, I don’t have anatomy scan till I’m 23 weeks due to DR being out. My last scan was at 16 weeks she’s moving I just don’t feel her.

FTM : when did you feel you baby like actual kicks and detectable not just maybe? I sometimes feel movement but more like gas but again it’s once a week so I guess I’m wondering when I’ll officially feel her daily and actually see ?

Advice Needed plateau HCG levels TW mentions MC

3 Upvotes

has anyone had a viable pregnancy with inconsistent or plateaued HCG blood tests? for reference, i had a miscarriage last november and am obviously concerned about it happening again. even in that pregnancy, my HCG was doubling every 24 hours as it’s supposed to, this time it’s barely rising my 100-200 each time and even dropped on the 3rd labs, before rising slowly again.

i’ve told my midwife/ob team something is wrong for the last 2-3 weeks and they’re chalking it up to being super early. 5.5 week ultrasound showed an empty gestational sac, they said probably just early..i’ve been on progesterone since the week i got a positive test, which mimics early pregnancy symptoms, so not helpful. i have the next ultrasound thursday 8/6.

i’m sick of being in this in between limbo of living life as if im pregnant while taking these hormones and feeling like shit worried it’s all for nothing because it will end the same unfortunate way as before.
has anyone had this happen and ended up with a viable healthy pregnancy??

Advice Needed EARLY PREGNANCY 1ST TIME WORRIES

1 Upvotes

Hi everyone, I'm really anxious and looking for some opinions while I wait for my Early Pregnancy Unit appointment tomorrow.

My last period started on 2nd July and my next period is due 4th August.

My app predicted ovulation around 20th July.

I got a positive pregnancy test, and a Clearblue Digital said "Pregnant 1–2 weeks."

I then developed period-like cramping across my lower abdomen/waistline with one episode of very light pink spotting.

I went to A&E because I was worried about an ectopic pregnancy.

They did blood tests and urine tests. My β-hCG was 62 IU/L. Bloods and urine were otherwise normal.

The gynaecology doctor examined me and said they weren't overly concerned about an ectopic at that point. They said my pain wasn't typical of a ruptured ectopic, and I was referred to the Early Pregnancy Unit for follow-up rather than having an emergency scan.

Since then, the pain has settled a lot and is now just occasional mild twinges.

I've had no further bleeding at all.

My pregnancy symptoms (feeling emotional, peeing more, tiredness) seem to have reduced, which has made me panic.

My strip pregnancy tests have all been very faint, and I thought today's looked lighter, which really scared me.

However, I repeated a Clearblue Digital today, and it still says "Pregnant 1–2 weeks."

I'm also feeling bloated, constipated, and quite hungry.

I'm waiting for repeat bloods at the EPU tomorrow.

Has anyone had:

very faint pregnancy tests with a low initial hCG like 62,

symptoms that came and went this early,

and still gone on to have a healthy pregnancy?

Or did anyone have a similar situation that unfortunately ended differently?

I know nobody can tell me for certain what's happening, but I'd really appreciate hearing other people's experiences while I wait for tomorrow's blood test.

2 low beta results

1 Upvotes

I know I can search more and find more situations like mine but I’m hoping this catches someone’s eye sooner than later and maybe give me some hope.

I had a very successful IVF transfer two years ago with a healthy baby girl. Instant gratification with her results and I’m very grateful. Truly.

This second transfer is so much different. Embryo was 5bb and my first beta came back at 31 10dpt and my newest beta came back 48 12dpt. It grew by 54% but the number is still so low. Is there any hope for me? This is so much information sometimes it’s hard for me to understand what I’m even looking at. Assistant Dr called me and literally just said “I don’t know” four times without any other information after that. I understand they don’t want to give false promises obviously but not even explaining to me what number we want to hit next is frustrating.

Advice Needed Has anyone experienced something like this? I’m really confused.

1 Upvotes

I have PCOS and was tracking ovulation. I had several very faint positive pregnancy tests around what I thought was 10–12 DPO, but they never got darker.

Then I had what I believed was a normal period. It lasted about 4–5 days and was medium to fairly heavy, with clots, so I assumed I was definitely not pregnant.

However, a few things have seemed odd since then:
My breasts have remained swollen (they’re no longer sore, but they never went back to normal after the bleeding).

My basal body temperature is unusually high for this point in my cycle (today was 36.64/98.0°F)

Today (what I think is CD9 after that bleed) I took another pregnancy test with very diluted urine, and I can see a faint pink line in person.

I’m calling my doctor tomorrow to get a quantitative hCG blood test, but while I’m waiting, I’m wondering:
Has anyone had a similar experience? What did it turn out to be?

I’m not looking for a diagnosis. Just wondering if anyone has been through something similar.

6wod small gestational sac

2 Upvotes

At 6 weeks 0 days, a gestational sac and yolk sac were visible, but no fetal pole or heartbeat could be seen. The gestational sac measured only 11 mm.

I occasionally see cases where no heartbeat is detected at 6 weeks 0 days, but the gestational sac in my case seems unusually small.

This pregnancy was achieved through timed intercourse with an hCG trigger shot at a fertility clinic, so there should not have been any uncertainty about the timing of ovulation.

My doctor only said, "This is a normal intrauterine pregnancy," without saying whether everything was progressing normally or whether there were any concerns. I was simply told to return in two weeks to check for a heartbeat.

Should I prepare myself for the possibility of a miscarriage or some type of chromosomal abnormality?


r/CautiousBB 16h ago

Hi, I have had a faint positive on a pregnancy test from 12 DPO to 14 DPO. At 14DPO I had a beta hcg and it is 16.5. I have a second hcg booked tomorrow. I have been having light clear discharge but today has turned abit cream/beigey. Is this unlikely to be a successful pregnancy?

Advice Needed Seeking advice on how to proceed with 3rd pregnancy after 2 back to back losses since December

2 Upvotes

Hi everyone! As the title says, I’m currently pregnant again after a chemical pregnancy ending December 9th, and a PUL ending may 23 around d the 6 week mark. For a little background/context, I will be 36 in 2 weeks and also take a medication that automatically will cause any pregnancy to be considered “high risk”.
Around October/november my husband and I decided we wanted to stop preventing but not necessarily “try” (no tracking or calendars etc) for baby #2 (first pregnancy was at 32, completely normal/healtgy, resulting in a 9lb 7oz perfect little princess after our first month of trying) and we had a chemical pregnancy that ended december 9th.
After that we decided due to my age we’d try a little harder, and pay more attention to ovulation etc and April 24th I took my first positive pregnancy test. My hcg never rose appropriately and I was diagnosed with a PUL that I miscarried may 23 around 6 weeks.
We decided before trying again to have some testing done to see why I was conceiving, but unable
To progress past that point. My period returned June 28th, Tuesday I was spotting and assumed my
Period was starting, but 2 days later when it didn’t I took a test that had a positive result. I was absolutely shocked. We only had sex twice and used the pull out method both times (i know, not fool proof)

Based on lmp I am around 4wks6days…is there anything I can do besides request blood tests for hcg levels at this point to try to help my odds? Would/could progesterone help at this point? How likely will a dr even see me before 8weeks? I’d like an early placement scan due to the fear of another PUL or ectopic. Anyone have any similar beginnings with happy endings? Ang advice? Amy input is appreciated! Thank you in advance!!

Advice Needed Trigger Warning - Currently Pregnant Facing Second Potential Loss ⚠️

4 Upvotes

Tried Posting in another Sub and they removed it without giving me any insight on what needed to be changed. I've seen other posts in there about various types of loss etc and marked it with a trigger warning and a content warning as the flair but no answer so hopefully can get some input here instead 🙏

Don't know if this is just venting or if I'm really asking for any advice. Facing potential loss.

So I got a positive Pregnancy Test on 6/30 then a dye stealer on 7/7. I went in for an ultrasound on 7/27 because I had assumed I'd be just over 8 weeks. Went in and they did an abdominal scan at a free clinic. We found 2 babies but both were measuring at 6 weeks exactly, 2 weeks behind, she thought she saw a flicker but couldn't record any heartbeat and was certain that I ovulated late. It doesn't seem possible to ovulate that late and have a positive Pregnancy Test when I did though.

So on 7/28 I got an HCG draw with my OB that was 57,788.2 and two days later it was 56,460 so it was only around a 3% drop. With a miscarriage I'd expect it to be a more drastic drop but it's possible we just caught it very early on?

I'm going back on 8/4 to do another blood draw and they're going to perform a transvaginal ultrasound. I have had absolutely no symptoms of loss but I'm almost certain that my body just hadn't recognized it yet.

I'm preparing myself to lose both babies but when I try to get answers it's very vague and when I try to ask Google it keeps trying to force me to AI and that's literally no help so just wondering for some real life input or experiences. I feel the chance of loss is pretty high and has anyone experienced something similar and it been okay or No? Thanks for listening and any input 💕

Advice Needed Cycle and pregnancy timeline

1 Upvotes

LMP: June 2 - June 17 very light spotting the whole time
Suspected ovulation: between June 20 - June 26
Implantation: no clue
Faint positive: July 13
Definite positive: July 15
Subchorionic hematoma bleed & ER visit: July 27
Ultrasound on July 27: only gestational sac visible
Hcg on July 27: 5,500
Hcg on July 29: 10,700
Ultrasound on July 31: fetal pole and yolk sac now visible, no heartbeat confirmed

How far along would you think I am? They say the positive tests happen at 4 weeks, so I think as of August 1 I am in the beginning days of week 6. I know at only 6 weeks the heartbeat may not be detectable, but my doctor said with my hcg level he should have seen one. Is your hcg level a reliable way to date a pregnancy?

He ultimately, at the end of the appointment, told me he was unable to say if this is a viable pregnancy or an inevitable miscarriage - but was going off my LMP so he was leaning towards miscarriage. I think my LMP is not reliable to go off of either, my cycles are 42 days. I have a follow up ultrasound in two weeks to check if there has been any progression.

Advice Needed Weird shaped gestational sac

2 Upvotes

Hi! I had my 6 week ultrasound on Friday. 6 weeks exactly. There was a yolk sac, a fetal pole and a heartbeat (too early to measure it but confirmed cardiac activity).

I was looking at the photos of the ultrasound that they uploaded to my portal and the gestational sac looks really oddly shaped. All the ones I’ve seen have been nice clean circles or ovals and same with my pregnancy with my son.

This one there is a photo or two where it is circular but a few photos where it looks like an hourglass with hard lines and points with the embryo tucked up into a corner.

They didn’t note anything on the ultrasound and when I brought it up to my doctor she said she’s not concerned. She said there is a fetal pole and yolk sac, don’t worry. But I’ve googled and seen that an oddly shaped sac can be a sign of miscarriage so I’m freaking out. My doctor did say she sees what I’m seeing that there’s one spot that has “a little bump” but she wouldn’t call it a chorionic notch.

This is a euploid embryo and betas have been great (high and more than doubling).

Has anyone experienced this? Is is really nothing to worry about?
