We had our third ultrasound today and all is well with the cupcakes. Baby A measured at 7 weeks 2 days and had a heartrate of 136 bpm. Baby B measured at 7 weeks exactly and had a heartrate of 144 bpm.
Now, here is the confusing part. There is a third sac. It was not present at my first scan, but was there last week. The first thing my tech noticed was that the third sac had grown since last time. Last week, she called it questionable sac and labeled it with a ?. Today, she labeled it sac C and said it measured at 5 weeks 2 days, but there is nothing inside it. She said she would know more by my next ultrasound. What the heck? We only transferred 2 embryos, so I thought 3 sacs was impossible. Apparently, an embryo can split inside one sac or a sac itself can split? And its measuring exactly 2 weeks behind. How is that possible?
In the picture below, you can see how baby A's sac is huge and B & C's would be much bigger if combined.
They didnt seem concerned at the office. I got my congratulations letter and instructions to see my OB. I can drop to 2 endometrin a day and stop my estrace. I cant help but worry a bit about whats going on inside my uterus! I will say, we love these babies so much already and just hope A & B continue to be strong and grow appropriately. We want to hold them in our arms this September!
