womens deodorant/antiperspirant recommendations

Hello, i smell pretty bad when i sweat, and recently started using secret outlast (an antiperspirant deodorant) but have built a resistance to it after about 3 weeks, and it doesn’t really work anymore.

Does anyone know what i should switch to? Should i continue to use it whilst applying an antiperspirant every other day, try an antibacterial cream or just change deodorant? I’m so frustrated with spending so much money on deodorants just for them to not last/stop working

Also, weirdly enough, i only smell under one arm and not the other - does anyone know if this is unusual?
