Big day tomorrow

Wow! Tomorrow we'll be 6 weeks pregnant! Can you believe it's already been two weeks since I had my first beta and found out we were "officially" pregnant? These last two weeks flew by! But the bigger deal about tomorrow is it's......drum roll please...........ultrasound day!

So here's what tomorrow's ultrasound will tell us. If you remember from my ectopics, when I went for my ultrasound the gestational sac was seen outside of the uterus. This time we want to see that sac (or sacs) INSIDE the uterus. Now that I have no fallopian tubes we have a much better chance of NOT having an ectopic, but you never know so that will be one thing they check.

At this point if all is well, inside the gestational sac they should be able to see, at a minimum, the yolk sac and a fetal pole. The fetal pole is actually the start of the fetus and the crown-rump length will be measured. At this point it's so small it will be measured in millimeters. But this measurement helps to give them the "age" of the fetus. For example, I may be 6 weeks pregnant tomorrow, but perhaps it will measure a little smaller, like 5 weeks and 4 days.

They will also see if the heartbeat is visible. The heart usually starts beating in the 5th or 6th week so we may get lucky and see the heartbeat(s) tomorrow - and boy, I sure hope we do. If no heartbeat tomorrow, it could just be too early and we'd need to go back sometime next week to check that the heart(s) has started beating. If we see that heartbeat tomorrow, we can relax (just a little) as we'll have made it through this first hurdle. Ok, in the infertility world maybe this is really our 100th hurdle but you know what I mean. Miscarriage rates decline some after the heartbeat is seen.

And then there's the million dollar question EVERYONE wants to know - how many are actually in there??? The poll is showing twins still in the lead so we'll see if that holds true tomorrow. Like I mentioned a few posts ago - it could be one really strong one. Or it could be 2, 3, or if some split after the transfer it could be 4 or more. We just won't know until the ultrasound tomorrow. Now if there are multiples and they're each in their own gestational sac, we'll know they were separate embryos that survived. If any multiples are in the same gestational sac, we'll know an embryo divided after transfer, thereby creating identical multiples.

So with all of that, now we just wait...12.5 hours to go. Now I just have to figure out how I curb this excitement to actually get some sleep tonight. Good luck with that right??
