I read... somewhere...? That all have the protrusiona @ 12weeks, but if your tech is a good one they may be able to tell the diff... a girls protrusion will point down and a male protrusion will point out... or up. Does that make sense?

Anyway... when I was pg with Violet I had a scan at 13.2 weeks and my DP and I were sure she had a doodle. It was veeery obvious! I wish I had've asked the tech, because she might have been able to make it more clear that it was in fact NOT a boy... not sure how skilled she was tho.

Anyway, I hope that helped
