[ajsmummy]

Here is my 13 week scan i'm not sure if you can see a nub as i have no idea what i'm looking for. I don't mind what sex the baby is but secrectly i'm kinda hoping for a girl as i already have two boys. Daddy wants a boy though as this is his first baby. Any guesses would be amazing. thankyou :) x6357
