Common: One of the side effects of depo provera (medroxyprogesterone) is prolonged and/or heavy bleeding especially the first 12 weeks. If a gynecologist gave it, he/she probably has an after hours answering service. Call the office and speak to the on call physician. I usually treat depo patient with a couple weeks of oral provera to thin out the lining much faster and control the bleeding.
