Yeast infection

Trini
So I think I have a yeast infection and I ALWAYS get them and Idk what else to do. I've gone to my doctor and she gave me some antibiotics for it and they didn't work for me, I've drank lots of water and everything and it just won't go away!!!! I have such a funky smell down there and it's so embarrassing bc i can't even have my bf go down on me without me feeling embarrassed!🙄 i bought a treatment from walmart and I still haven't started it bc I'm scared of doing it. Any comments? Ideas ladies ?
