Need more info: It's difficult to answer without more information! Have your menses usually been regular, have you used oral contraception methods, could you have been pregnant and had a miscarriage? If this continues the you should see a gynaecologist for further evaluation! I'm sorry but with the limited information you provided I cannot give you a specific answer
