Underarms constantly sweating, causing boils when shaving, 28 weeks pregnant

Mamas I am frustrated.. I have sweat so much more daily even in cold environment and I know it’s the hormones. I’ve switched countless deodorants, (the last one being the “Native” brand that was nearly $12. Nothing has worked and that’s fine, I’m just frustrated. I’ve showered 3 whole times today because of just random sweat outbreaks but not only that, I smell like funk, the deodorant doesn’t cover any odors. I’m in a cold environment since I keep my house cold but it’s getting frustrating. I don’t want to have to keep changing and showering a million times a day. I am getting boils or pimples under my arms now too, (I’m sure that’s because I shave almost weekly since my hair grows so fast from the pregnancy)

I’m just frustrated. Any tips? I’m going to be icing my underarms tonight but I’m so fed up with no deodorant working.
