I Shaved Before My Period. The Day After My Period

I shaved before my period. The day after my period I noticed that my labia majora was dry and peeled. Soon after my labia majora was red and itchy but with no sores, discharge or bleeding. The inside of my labia majora near my labia minora is also red and itchy. I was treated as a yeast infection but it has been 8 days. I have used Cortisone, Desitin, and another cream and none have worked.
