HELP VYI

Guys, It's terrible. I'm pretty sure I have a yeast infection. Idk if it's because I have been taking antibiotics for 2 weeks already or if it's because my boyfriend fingered me recently, (which he always does and he is clean) so, it's weird... however, I don't want to tell my mother, and I don't want to go to the gynecologist. WHAT IS THE BEST REMEDY/MEDICINE TO BUY?? Otc and not otc? Please help, it's itching so badly. 😭😭😭
