I really wanted a boy - always said I wanted my eldest to be a boy. To try and not be too disapointed I convinced my self it would be a girl, baby had a heartbeat over 140bpm which apparently makes it more likely to be a girl, also at my 12 week scan they put my date back by a few days so also thought this meant it would be a girl as girly sperm live longer but travel slower!!!
So at the scan we asked to find out the sex, and baby was laying there with legs wide open and even thought I could see a little winkie I still waited for the sonographer to confirm it!!
