Call gynecologist: You may be pregnant and having a miscarriage. Contact your gynecologist. An exam, a pelvic ultrasound, and, if need be, HCG levels will decine the issue.

Hard to say: you may have had a spontaneous abortion or just an irregular, heavy cycle. Maybe it's time to get on birth control and have your partner use condoms. Be responsible and do a home pregnacy test, see your GYN for an exam and blood testing and be responsible for your own sexuality.
