Hello, i am 21 years old. I am an unmarried.I am attend age at 10 years. But now within 8 to 10 months the irregular periods started. Sorry to say, I have intercourse with my fiance and also doing hand job. But now i have stopped those things. I was going to doctor and ate pills. But on that time only the period will come. And the next month the same thing started. Now my weight is too high.What is the solution for this problem? And What is the reason for this?
