We had our first prenatal ultrasound this week. Our clinic has an online portal where I can go to see my lab results and med instructions and upcoming appointments, etc. It's pretty cool. What was really cool was when I last got on the portal and it said my next appt was for "Ultrasound (obstetrical)." Wow - an OB ultrasound - I thought that might never happen. Anyway, we got to see the gestational sac and the beginnings of the fetal pole - it was really neat. (We were kind of hoping for 2 sacs - twins -but I discovered that I was actually relieved to be only having one baby. It's much more likely that I can have a natural delivery and more success breastfeeding than it would be if I had twins.)
Even though I'm just barely pregnant - of course, I'm thinking about my due date. The best that I had figured, I would be due Oct 7th. I thought I was 5 1/2 weeks at that ultrasound. (I used online FET calculators, several of them, to confirm my calculations.) But the nurse said I was only 4 1/2 weeks along. I asked how she figured and she said a bunch of stuff about how it would be 2 weeks at retrieval, but with FET, they use the transfer date, then go back how many days old it is, etc. It sounded like what I had figured. Then she told me I'm due Oct 13th.
WHAT? Oct 13th is when I would be due if we went strictly by my LMP (last menstrual period - the usual way of calculating due dates.) But that doesn't work here. There were only 12 days between my LMP and the FET and at that point, the embryo was already 5 days old. We're missing a whole week in there. PLUS, if I was really only 4 1/2 weeks, my beta wouldn't be 11,000+ nor would we see a gestational sac already. I don't get it. Why would they just go by LMP?
I don't want to be argumentative, but it's frustrating. I don't want to be off by a week for my entire pregnancy. Hopefully, I'll get a different nurse this week and I can ask her. They are expecting to see the heartbeat this week - which I am really looking forward to. Each time we go, I believe just a little bit more than I really am pregnant.
On another note: we're looking for a creative way to announce our pregnancy to our church. There are 2 friends that we MUST tell before anyone else finds out - and we're doing that next weekend. Then we want to announce it to our church family, but we need a creative way to explain embryo adoption. We don't want to just say that we're pregnant. We want everyone to know that we're pregnant with our adopted child. We're excited about how the Lord has led us to this point. Anyone have any ideas????
