At 12 weeks my boy was 150-160, and at 16 weeks he was 140-150 since then he has been about 140. it's normal for it to be fast at first, and for it to slow down through your pregnancy.
I thought I was having a girl because the heartbeat is always high and I was following the wise tale but I found out I'm having a baby boy :)
Heartbeat is just a wise tale. they say if its 140 or above its a girl but I'm having a girl and her heartbeat has always been 130's
Every appointment I've been too since 7 weeks has been 150.
