I haven't had a period in two years im 20 can i get pregnant what could be wrong witg me i started when.iwas 13 stopped for 2 yrs got it 2x ayr?

unlikely pregnancy: There are a number of reasons to stop having a period once you start. The diagnosis at the top of the list is always pregnancy, but you wouldnt be pregnant for 2 years. The other possibility is low weight, eating disorder, excessive exercise, and hormone imbalance. I would see the advice of a gynecologist for further testing.

many possibilities: Get checked. A thorough history, physical exam and naybe some blood work can rule certain things out and hopefully find the reason you are not having periods.
