23w pregnant-need a GOOD deodorant!

My entire pregnancy, especially lately, I get so hot easily and no deodorant I've tried has done well. I always feel wet and have b.o. just a couple hrs after applying it. I've tried Tom's, different secret deodorants, old spice, dove, and schmidt's. They all smell good at first and then within a couple hrs I smell bad. The schmidt's deodorant irritated the crap out of my underarms (didnt use to before getting pregnant) so I also need something for somewhat sensitive skin. Thanks in advance
