Twin genders

Krystle
I went to an ultrasound yesterday at 15 wks. The tech said she was pretty sure on baby A but that it was still early. She then looked at baby B and said she is even more confident on B. At 15 wks how sure do you think this is? I don't want to be getting my hopes up. Also when the dr came in he said they have their own placentas but appear to be the same sex so they still might be identical. Surely they both wouldn't say that if they weren't pretty certain right? Lol
