Curious

Has any one been pregnant with a boy who heart beat was 152 I couldn’t find out the gender at my ultrasound cuz the baby was head down facing the opposite side legs closed being lazy but I took a ring over my belly and it goes back and forth so fast and I know myths says boys just Curious plus I only throw up once in morning nothing more I’m going with my gut I have 3 girls and 2 boys already and all my boys act the same and my girls act the same when I’m carrying them🥲

Update I KNOW HEART RATES DONT DETERMINE GENDERS I JUST WANT OPINIONS
