weird yeast infection?

So about two weeks ago i have a nasty sinus infection and was prescribed some antibiotics. I took two of them everyday for a little over a week a few days after i finished them, i noticed my vaginal opening was a little red and itchy. So i slapped some coconut oil on it and bought some AZO yeast infection meds. I was feeling better, until i woke up this morning with the left part of my clitoris inflamed. I think it’s part of the yeast infection but it’s never happened to me before. Can someone explain?
