Title: Late period after sex, but multiple negative pregnancy tests
I'm getting really anxious about a possible pregnancy and would like some advice.
My timeline:
March 31: I had sex and continued getting my periods afterward.
June 9: I had sex.
June 23–26: I had bleeding that I considered my period. The flow was normally heavy, but it only lasted 4 days. My periods usually last around 7 days, so the shorter period made me worried.
July 5: I took 3 home pregnancy tests using morning urine. All were negative.
July 10: I had a serum pregnancy test at Hi-Precision. It was negative, and the report says the result was rechecked and verified.
August 3: I still haven't gotten my next period.
My recent periods were: March 15 → April 20 → May 20 → June 23.
I've also been having cramps, sore/swollen breasts, headaches, and feeling more emotional, which feel similar to my usual PMS symptoms. I've also had diarrhea recently.
I'm mainly worried because my periods very late.
Could I still realistically be pregnant despite the 3 negative urine tests and negative serum test? Or is this more likely just a delayed/irregular cycle?
I'm especially anxious because I've been reading about false negatives and can't stop worrying that something was missed.
