Product recommendations for groin rash?

Ma

I am less than a week away from 3rd trimester and have started developing a rash in the crease between my thigh and groin. I think it’s due to moisture and friction as that are is bigger than before pregnancy. I tested negative for a yeast infection and positive for BV but that’s being treated and the rash is still present. I’ve never used anything other than aquaphor on it. Aquaphor relieves it for a bit but it’s still there. I know I have less hip mobility and have been waddling more which adds to the friction but honestly cannot be helped. Anyone have some good products to recommend. I have a feeling this will remain for the rest of my pregnancy so I’m look for relief.
