Is this normal?

Is it normal if my discarge is kind of lumpy? My vagina kind of hurts from my boyfriend being a bit to rough could that have anything to do with it or if he not being rough theres sumthign wrong with me?

It sounds like a Yeast Infection. Typical Yeast Infection symptoms are, vaginal itching, vaginal discharge that may be thick, white, and lumpy like cottage cheese, vaginal soreness, irritation, or
burning, rash or redness on the skin outside the vagina (vulva), burning on urination or painful vaginal intercourse. You can try Monistat or Vagistat to get rid of it. You can buy those at any drug store. Creams are very messy from my experience. I prefer inserts. I usually use Monistat 1 Combination Pack. It has an insert and an outer cream to help relieve it instantly.

If it is a yeast infection what will happen if I dont treat it? Also what will happen if I do use one of those and I don't have a yeast infection?

If you don't treat a yeast infection it will only keep getting worse and can move higher in to your vagina. You can also develope a bacterial infection if you don't treat a yeast infection and bacterial infections can be very dangerous. Nothing will really happen if you use those and don't have a yeast infection. But I would seriously see a doctor to find out what is going on. If they say you have a yeast infection they will either give you a pill or you can opt to use the ones from the store.
