Gender Guess

Antoinette

So based on the heart rate theory for gender 140 and below is a boy anything above is a girl … at 7 weeks baby heart rate was 120. I got my ultra sound yesterday 12 weeks and baby heart rate was 155 🤔. Of course I should just wait lol. I’m anxious, what’s your thoughts and experience?

9/14 Update- It’s a boy!
