We don't know and didn't find out last time either. I actually liked having people guessing and never let it get to me at all. I usually just nod and smile. Everyone I have shown my ultrasound pic to says it looks like a boy - really? It looks like a baby to me - I can't see any gender identifying features. Last time DP's sister was certain I was having a girl from the way I was carrying. She hasn't seen me this time though.
