Well, my RE gave us a 50/50 chance of this being a viable pregnancy. I am fairly certain those odds were totally made up, so there’s that.
Having done this initial ultrasound now twice before, I kind of knew what to look for. We were in with the ultrasound tech (who I’ve had for almost all of my ultrasounds since we started fertility treatments in 2014) first, and then saw my RE. Right off the bat I was relieved because I could tell that the sac was in the uterus. They also saw a yolk sac, but no fetal pole yet. My RE said that the sac size and structures look like a normal pregnancy at about “5 and a half weeks.” According to my calculations, I thought I was 6 weeks today, though my RE had me at 5 weeks 6 days. There was no heartbeat (which I guess makes sense with no fetal pole).
My RE said that it’s possible that the embryo took a couple of days before implanting, which would account for the lower HCG numbers as well as today’s ultrasound results. Or, this is another nonviable embryo. She said they want to have me back in 11-14 days and if at that point there is no heartbeat or it’s fallen even further behind, we’ll stop meds and assumedly talk about ending the pregnancy.
I’m trying to stay hopeful. It seems totally feasible that the frozen embryo just took it’s time implanting. It’s going to be a very long 2 weeks. I’m scheduled to go back for another ultrasound on July 5.
