Im also in the same boat. I have a son and am pregnant with our second maybe last child?? and we were told by the sonographer at the 20 week scan that he thought it was a girl. He looked twice and said "i think its a girl" both times. I wouldnt mind if we had another boy but we did 'try' for a girl so we are hoping pink. Some days im certain the sonographer was right and others i also imagine the midwife saying its a boy. Friends of ours just had their bub and they were told a girl and had a boy!! 9 weeks and ill know for sure!
