I just got my first vaginal yeast infection. I decided to take monistat 3 however, my yeast infection was very minor and after I took the first one all my symptoms have completely vanished. I decided to not take the other two applicators and it’s been a few days and I seem to be normal- is it okay to stop taking the monistat 1/3 through the treatment? And also when is it okay to start having sex after treating a yeast infection?

I'm suffering from a yeast infection, I've tried to treat it with the over the counter monistat, it relieved most of the symptoms but they came back a few days later. My doctor prescribed me the one dose of diflucan, if I take it today how long will it take to cure my yeast infection? and how long should I wait before having sex?
