I'm due in like 15 days but as soon as I got pregnant my Dr told me it was most likely a boy. Every appointment I went to he would say "yup that heart beat is all boy. So you could imagine how surprised I was when 20 weeks came and my examiner said "it's a girl!". It kind of caught me off guard. I did a home acid test after that (peeing in a cup of baking soda. If your trying makes the solution all fizzy and foamy you're high in acid and if it doesn't you're low in acid and it is suggested that if you're having a boy, your urine's acidity is higher) and it came back super high in acid. So I was even more confused. I went to a 3D ultrasound place for a second opinion and it turned out to be a girl, but her heartbeat is just very boy-ish. And who knows why my urine is so high in acid....
