Well I asked my Ob when he did a scan at 16 weeks and he declared it was a boy. So DH and I spent the next 5 weeks before our 21 week ultrasound getting excited about our son. At our 21 wk ultrasound we asked the sonographer to check it was a boy and he told us it was not a boy after all, but a litlle girl! OMG. I asked him to check 3 times and he said he was very sure, but I am still having trouble believing it. I don't think I'll really believe it until my baby is in my arms. Curiosity will probably get the better of me and I might just have to book in for another scan...
