Got an ultrasound with our twins around 15 weeks when we found out baby b was a boy and were pretty sure baby a was a girl but baby a wouldn't open its legs very much so we weren't positive. Just went back yesterday for our anatomy scan and once again baby b was a very obvious boy but baby a still wouldn't open its legs that much. If it did it would be really fast and then close them again. We were wanting to tell our families the genders at thanksgiving but I'm so afraid that since baby a is stubborn that we will tell them and it will be wrong lol. The tech said both times that she was pretty sure it was a girl but wasn't 100%. I so badly just wanted it to be confirmed. I can definitely tell a difference between the both but then I keep going back and thinking well what if. . . What do you all think? Anyone else had this problem? Think it's safe to go ahead and tell the family?
