Hi there. You may have an overgrowth of yeast. Have you ever had a yeast infection? They are fairly easy to treat but for your first one ever, it should be diagnosed by a doctor. There are over the counter things you can use from the drug store or the doctor can prescribe a pill. But we can't diagnose you here on the internet. Women have all sorts of discharge but typically it doesn't itch. That's the part that makes me think yeast. good luck
