STD or….?

Hey! So I don’t really know what else to do here…. Last time I got my period I had bought some pads from dollar tree (they had aloe in them) and I had started to get some vaginal itching but thought it was from the pads so I blew it off. Once my period had ended, the itching was still there, so I thought may be a yeast infection so I got a 7 day treatment for it after I had spoke with one of the nurses at my OB’s office. And here we are, 2-3 days after finishing the treatment, and still itching…..what could it be?
