Heat rash

Robyn • 2 little girls and expecting baby #3 in Sept. ❤❤

This is my third pregnancy but my first ever through the hottest months of the year. I am hot all the time and sweat constantly. I know, not pretty, but it's part of it I guess. I have been suffering from a heat rash between my thighs and under my breasts for about a week now. I was wondering if anyone else is having issues with this and what I could do to try to help heal it. Thanks in advance.
