Is this a yeast infection?

I was taking antibiotics for an ear infection and I know they go hand in hand, but it doesn’t burn when I pee, and I don’t feel the need to pee all the time and not being able to. I have no abnormal discharge or odor but I am itchy on the inside of my vagina. I did the 3 day monistat treatment and it helped but I still feel a little itchy.
