It's different rates for the duration of your pregnancy if it's a boy or girl haha. Not just a base rate for the whole thing. There is this calculator for it online.
Mine started out in the high 150s & low 160s early in my pregnancy but now it's always 144 or 147 & I'm having a boy!
My first heartbeat was 162 and I'm having a boy so those aren't really true anymore. Same thing goes for my best friend. She was in the 160's with her son
My baby's was 163 and we found out today we're having a girl :)
My baby boy has a heart rate in the 150s. 35 weeks now. :)
mine was 154 so that means ot a gir! (: lol i still dont know what im having
Mines 140 everytime & it's a girl
Highs are girls lows are boys is the fable my baby has always been between 130-140 and its a boy!!
