So we had our ultrasound yesterday and the fetal heart rate for both babies was right at 90.
We were technically 6w5d based on the frozen transfer. He did say implantation could have been slightly later since the embryo was dividing into identical twins. However they were measuring for 5w6d and 6w0d. We have to go back in on Monday for a follow up... But I'm totally a wreck and haven't found much of anything to be useful. I don't know of the heart rate is more concerning or the size (or something else that I didn't know to ask/write down)
Does anyone know if it's normal for babies to be a few days behind developmentally, but at the right date? (We got a positive HPT just 4 days after the transfer, albeit very light, so I know they had implanted by then unless the other embryo implanted to start producing HCG, grasping at straws here). And on this site, it says 6-7 weeks, the 90bpm is still in the low range of normal. But other things I read say that it should be over 110. I'm making myself crazy, I realize, but any thoughts might easy a stressed mind.
We have to go in on Monday for follow up and don't know how I'm going to make it that long.
