No heartburn

Is it a myth that heartburn means you are going to have a hairy baby? I had a lot of hair when I was born, thick dark curls and my mum said she suffered bad with heartburn but I haven’t had it through my pregnancy does this mean my little girl is going to be bald? My partner had hair when he was born as well just lighter, I want to believe it’s a myth as I would love my princess to have hair 😍👶🏼
