I Never Ever Used To Have A Problem With Under

I never ever used to have a problem with under arm odor. When I used to sweat, it smelled like normal sweat and it wasn't that noticeable. The past two months I've been sweating mainly when I'm anxious/playing sports. And there's a diff smell to it. I shower regularly and it would still stay. Would cetaphil antibacterial soap help rid the odor? I've tried everything. I can't stand wearing deodorant because the smell goes through.
