One of the most common side effects of the shot or Depo-Provera is irregular bleeding. The shot contains a high level of progestin hormone which can interrupt a regular menstrual cycle. Many women experience light spotting, longer periods or no period at all. That begin said, it also takes the body a few months to adjust to a different level of hormone. Give your body some time to adjust, ideally 2-3 injections or 6 – 9 months. There are also other effective methods of birth control that might work better with your body. Contact your doctor or make an appointment at Teen Clinic for a consult about other birth control options.
