So I went to my 12 wk 5 day appt today..baby had a strong heartbeat of 146!! I have three little boys who had heart rates of 165+...but Ive always heard that girls have a higher heart rate and boys have a lower heart rate!! I said to the Dr." Oh it's gonna be a boy and he said no,no,no that's just a myth!" Lol please give me your stories!!! And what do you think this little one might be?
