Hi there and welcome. Ugh, sorry to hear. A bad vag itch can drive you nuts! Fungal overgrowth can cause this, yeast being the most common. Although yeast infections usually have clumpy discharge that is odorless but itches, not always. You can try some vagisil wipes for now. You've never been diagnosed which is the best thing to do with your first yeast infection. Can you tell your mom and see your doctor? They swab it and tell you exactly what it is. Then treat it. Otherwise, you can talk to your mom about over the counter remedies like Monastat. Yeast and fungal overgrowth can happen for lots of reasons. Great that you don't douche though and are aware of the ph balance of your vagina. You are exactly right on that. But every woman can get these overgrowths. Antibiotics are a prime suspect if you've been on those recently. Anyway, you can eat probiotic yogurt (I like Danon Activia) or take a probiotic supplement. Cut back on sugar. Wear loose clothing, cotton underwear. Air it out occasionally (maybe sleep with no underwear on for example). But talk to your mom (nothing to be embarrassed about . . . babies get yeast infections!). good luck
