Today we went for our second sonogram with the RE. The good news is that we had a visible / detectable heartbeat and that the gestational sac, yolk sac, and fetal pole had all grown just as they should over a one week period. The not so good news is that I am measuring a full week behind (I am 7 weeks and 2 days pregnant but am only measuring 6 weeks 2 days pregnant). The crown to rump measurement today was 5mm, up from 2mm a week ago (apparently at our first sonogram one week ago we were only measuring at 5 weeks 2 days pregnant instead of 6 weeks 2 days pregnant). The RE stated that she has seen plenty of women measure behind and still have a viable pregnancy and deliver healthy babies. Right now it is a positive sign that the growth over a one week period was typical growth. However, we must be cautiously optimistic at this time as things could also go the other way, in that the pregnancy could just stop progressing.
We will be back at the RE's office next Monday for a third sonogram. It is all of our hopes that the growth will continue just as it should, or, even more optimistically, bridge the gap. We also hope that the heartbeat continues to get stronger. If these things do happen for us, we will be released to the OB for the rest of the pregnancy. If not, we will have to deal with the situation that presents itself and move forward.
