For those of you who have the information. I'm curious if there's a correlation between early heart rate and gender.

LO's heart rate at 6 weeks 5 days was: 148/149
Baby #2's heart rate at 6 weeks 5 days was: 139/140

I had both first ultrasounds at 6weeks5days! Both were performed on the 4th of the month too. Haha.
