Im twenty weeks and I have a small rash on my breast ! I was guna ask my doctor tomorrow
Its a fungus infection between your breast due to moisture and the bra is dark and warm. A normal antifungal cream for a few weeks will help
Check if your bra size has changed. It could be too tight causing you to sweat more.
I agree. Try and antifungal cream or have your ob rx nystatin cream (used for yeast rashes caused by heat and moisture and hormones.)
