I think I have a yeast infection, and I think its a pretty bad one, but I’m not sure because its my first one. my symptoms are: itchiness, burning, and excess discharge. It itches SO badly, it hurts so bad I want to cry sometimes, I don’t know if thats normal for a yeast infection, but anyways which treatment is the most effective: 1,3, or 7 day?

I thought I had a yeast infection so I bought Monistat 1 over the counter & used before bedtime last night. Woke up this morning with serious pain, swelling & redness down there. Could I be having an allergic reaction to the Monistat? I’ve used it before with no problems, but this is bad!!
