Concern over hot bath TMI

Brittany
Has anyone had the problem of a zit in their vagina? I know that sounds disgusting, but I'm an active runner and I get sweaty down there and for the first time since I've been pregnant and ever in that matter have found a zit. No it's not herps, I have std testing every year. But I was told to take a hot bath to shrink it, which work. But now my body feels weird, like my babies heart beAt is going crazy. I know I might just being crazy but I know hot baths are out of the question. But could it effect the baby? Sorry tmi
