Fetal doppler


I bought a fetal doppler and i love it πŸ’—

I use it every other day, its amazing sound to hear πŸ˜€ i'm 18 weeks and 3 days . from the First time i heard the heart beat at 13 weeks at the dr it said 145 beats and on mine my baby rate 145-150 and up . i was told from other ladies that anything over 145 and up its a girl and anything below 145 its a boy !! What do you think? I will find out in a week what im having... can't wait
