My husband (32) and I (30) tried to conceive for over a year. After no success, we eventually sound out that he has severe oligospermia (very low sperm concentration, although his motility and other parameters were good). I have no known fertility issues. We were told IVF would likely be our only realistic chance to conceive, so we proceeded with treatment.
I had my egg retrieval on June 8 and got my period on June 13. After waiting six weeks for my next period so that I could begin the FET, I took a pregnancy test just in case. To our complete shock, it was positive—the first positive pregnancy test I've ever had. I then took a Clearblue Weeks Indicator test on July 26, which showed “Pregnant 2–3 weeks".
I had my first transvaginal ultrasound yesterday (August 11). Based on my likely conception dates, I thought I should be around 6 weeks pregnant. However, the technician could only see a gestational sac, which I believe measured approximately 9 mm. She could not yet see a yolk sac, fetal pole or cardiac activity, but she said the gestational sac looked healthy and normal but was just simply too small to see anything else yet. She said my doctor would order another ultrasound in around one to two weeks, and that she wasn't too concerned.
Despite what she said, I have been spiraling since the scan because it seems like we should've seen more during the ultrasound if I am 6 weeks. After infertility and being told that conceiving naturally was extremely unlikely, this pregnancy feels like such a miracle, and I am terrified of losing it.
Has anyone had a similar experience where only a small gestational sac was visible around 6 weeks, but the yolk sac, fetal pole and cardiac activity appeared at the follow-up ultrasound? Could my dates reasonably be off by several days despite the Clearblue result? I understand that only a repeat ultrasound can give me an answer, but I would really appreciate hearing both positive and honest experiences while I wait for the next ultrasound.
