Over the counter?

Okay so, for about a few days now i have noticed a fishy smell down there and i did some research and it looks like its a yeast infection. Its really annoying it makes me feel insecure and uncomfortable but i dont want to go to the doctor im scared of them and specially getting looked at down there so i was wondering if there is some meds that i can get at a local drugstore over the counter to fix it. Comment down below. And thank you lol.
