My baby's has always been over 150 and he's a boy. How far are you?

There is no way you can be sure-even at 20 week u.s they can't guarantee the sex although more often than not they're right :)
Both my girls heart rates were above 160 & I know a gf baby boy's hr was 145 so maybe if I was to say either or I go for girl :)
Congrats on your pregnancy x

Some say over 150 is a girl and under is a boy but others say 140. There are studies that say the heart rate to gender is not accurate.   Mine started at 158 but it was moving around alot, so it was elevated.  now at 18wks it's been arround 147 each time they check it.   I think the best way to figure out is the ultrasound that you have at around 20wks for the anatomy scan.
