odor ?

so lately i’ve noticed a weird vagina odor and i don’t know why or how to get rid of it. i had a yeast infection a while ago and like i had it for a while before i realized (i’d never had one before, i just thought it was some sort of rash from working out in a thong and like the friction and moisture mixing) and i went to the doctor and they gave me a cream and a pill to help it go away and i was good, the smell was gone and the itch that i had was gone. but i feel like shortly after there was an odor again. my boyfriend pointed it out once maybe about three or four weeks after the yeast infection went away but i figured that like i’d been sweating and i was just about to get in the shower so i thought it was sort of just a sweat thing. but i’ve really noticed like the last week or two it just really unpleasant, it’s not a “fishy” smell i don’t really think, but it’s just not good. i feel like i can smell it when my pants are off and i feel like the smell is even there right after getting out of the shower. i’ve been trying to drink more water, i’ve been drinking water with apple cider vinegar, i have used the cream that the doctor gave me for my yeast infection just incase that’s what it was, i put a rag with water and ACV mixed together on it, and i just really don’t know what could be going on. when i had a yeast infection it itches but this doesn’t itch. my boyfriend is the only person i have sex with and we use condoms, and i got tested for STD’s when i went to the doctor about my yeast infection and i’m fine. i just started taking probiotic vitamins like a week ago. i started taking a different birth control, but i took this same pill about a year ago and switched to the generic brand and switched back a few weeks ago. but i don’t know what’s going on
