Well, this is an interesting topic. DH and I both really wanted a boy - the week before my 19 wk u/s was so stressful, I honestly didn't sleep the 2 nights before, I was so stressed. I kept telling myself how selfish I was, but I didn't know how DH or I would cope with the disappointment of a girl. When we went in, the u/s lady couldn't see for ages, then finally she found what she thought was a penis, and DH literally jumped out of his chair with joy. So she warned us that it wasn't 100%, so we will have to wait until the day to be sure. It's just such a taboo thing to admit that you really have a preference instead of saying 'I don't mind, so long as it's healthy', that I have always been too scared to admit any of this to anyone apart from DH!
