Boy Girl Question!!!

👧🏽Lindsay👶🏽 • 👰🏻🤵🏿💍 2012. 👧🏽🎀 1/2016. 👼🏽MC Oct ‘17. 👶🏽🎀 #2 born 12/2018! #2 was born with medical and special needs. My girls are the joy of my life💕
So, from the first ultrasound, I felt that this baby would be a boy (despite thinking that I would have all girls prior to getting pregnant). Almost everyone in my family agrees that they think it's going to be a boy. And even the needle test says boy!
However....today I went with my hubby to hear the heartbeat. I was surprised that the hr was 150 bpm! The hr was only 122 at my first appointment. 
My question for you all is: did you have a boy with a higher hr? I've just always heard that boys tend to have lower HRs. Was that true for you?
