Heart rate comparison from first born

Maylon • Happily Married : Mom to 2 Boys : Cason Kole 12.8.16 💙 Colby Lee 9.20.18 💙

Just curious- my first born had a heart rate of 174 when we went to our 8 week ultrasound appt. today for our second child the heart rate was 173. Wondering if maybe it’s another boy...if anyone else has had very close heart rates with their LO’s and what the genders ended up being 😊 pic of ultrasound today too
