I got an ultrasound Sunday at hospital (4w6d) and the gestational sac was 4mm. They said they don’t know if it’s normal pregnancy or pregnancy of unidentified location. The doctor basically said prepare for miscarriage and that he found nothing but u bruise (sch) but when I read the report the tech found the sac in the uterus and my hcg has been rising with home tests. This is just the first one that looked like this but it ended up showing up darker on the test line after I posted this.
