Heartburn

I haven’t had heartburn the whole pregnancy and people are saying she might be bald which I’m sure I could use cute bows lol...just if someone says my daughter is a boy I’ll kill them with my mean face.

I’ve been reading that that’s not necessarily true but I’m wondering if any mommy’s have had no heartburn and a baby with hair ? Is it true because I’ve also heard there’s been studies that say say it is true . Basically everything says it’s 50/50 . But I wanna hear from you guys has anyone experience this
