Do you believe in the heart rate gender prediction?

Rebekah • Mommy of 2 amazing kids with 2 more on the way! Joseph`s wife! ✨
One of my twins has a heart rate of 175 & the other twin has a heart rate of 169. Me & my husband would love to have a girl & a boy but everyone's saying it sounds like 2 girls. Just wanted to see what everyone else thinks.
