Baby’s heart beat

Mollie

So I am probably just being paranoid.. but I’m a ftm and just had a doctors appointment this morning and she checked baby’s heart beat with the Doppler and she said “ok it’s around 145 which is normal” but said it in a way like it wasn’t supposed to be that low. I’m having a girl. But is this ok??? Is it too low? I know I’m probably just freaking out for no reason but I need some reassurance. Thanks everyone!
