Is this common? My husband and I have been the the OB or MFM for 3 different ultrasounds since 16 weeks, and we should have been able to see the sexes of the babies. They can't see! Even at the MFM appt, a 40 min ultrasound, the umbilical cord was always in the way and the legs were crossed on one baby. They THINK the other one is a boy, but they aren't sure. I really want to prepare for these babies, and if there isn't a girl in there, I also need to prepare for that.
Does this happen more often in twin pregnancies? I have heard that the sex is hard to see later on as they are more squished, but I am starting to get anxious as I just want to know! We are thinking of getting a 3D private scan if the upcoming 20-wk appt in radiology doesn't reveal sex. Are those more accurate for sex? I read recently how people on here were told mistaken sexes with their twins- is that more common too? I am paranoid that even if they see, they will get it wrong. I know this isn't the most important thing- so far the babies are healthy!- but I just want to know and didn't expect so much uncertainty! Anyone have experience like this?
