Does anyone have a deodorant recc or natural remedy?

I don't know when it started but my body has begun to reject deodorant. It wears off of I walk to the car, lol.  I even had swelling the other day but it could've been breast tissue causing my underarms to swell ginormously. At any rate, my BO has gotten worst--I've never had hair under my arms, ever, so I will attribute these changes to hormones. Anyone have a natural remedy for BO or mommy friendly deodorant?
