I had a private scan on Friday at 7 + 3 according to my cycle. Couldn’t see anything externally, and transvaginal showed only a gestational sac measuring 8mm, which the sonographer estimated to be 5 - 6 weeks. No yolk or heartbeat seen. Is it possible I’m off on my dates? I think I ovulate around cd 18/19, and the sonographer said I had a very retroverted uterus, could either of these explain why no heartbeat? I have a follow up scan booked for next week to check for changes, but wondering if I should ask for it to be done in EPU instead. Trying to stay positive, but this pregnancy follows mc 6 months ago and worried about history repeating.
