Hygiene questions please read :)

Hello everybody!! Ive realized a different smell around/in my vagina and it smells like body odor like the sweaty gross smell when you don’t wear deodorant on ur armpits. I don’t understand how it can be when I shower every single day. And it happens like 4-5 hours I get out of the shower I have a b/o smell. Is there a different wash I should be using? Different underwear? I don’t know what to do. It especially gets bad around my period cause I have a pad on. I had smelling like sweaty armpits. Nothing itches, hurts, or anything it’s just a b/o smell hours after a shower.
