I had an appointment to hear the heartbeat today. I am almost 15 weeks. The baby’s heart is at 160, which it has been all four times that I’ve heard it. My dr said “I’m betting there’s a little girl in there.” I know that’s just a myth and not a scientific fact by any means, but if my dr is willing to bet on it should I start thinking it’s a girl too?
I wouldn’t. With my first, ppl said he was going to be a girl bc he had that fast heart rate too, and he was a boy. Still, it’s fun to speculate. 
Nope. I think your doctor was just playing with you. Of course, there’s a 50% chance he/she is right!
