Yeast infection...

Hi, about a month ago I got treated for a yeast infection but I’m pretty sure it’s either back or it wasn’t treated all the way because my discharge has a faint cheese smell. No itching or burning, just the slight smell. I’ve been in and out of the doctors for being sick, and I don’t really feel like going again 😩 so any recommendations on store bought medications I can try?

(I’ll go to the doctor if it gets worse, but since I just have a slight smell I’m wondering if it’s a start of a yeast infection)
