2 days away from anatomy scan!!

My anatomy scan is Wednesday and I'm so excited and nervous at the same time. I never even thought I'd be that woman that would ever think of gender disappointment. We want a boy so bad, and I'm getting so nervous. Obviously we will be happy either way, little girls are fun too. But we've always dreamed of having a boy. My husband has referred to our baby as son as soon as I got pregnant. I keep reminding him to not do that. I don't want him to get his hopes up too high.
