Depoprovera effect: Depoprovera is one of the most effective forms of birth control as long as you get the shot every 3 months as directed. Failures are very rare. Irregular or absent periods are an expected side effect. Failure rates are 1-3%. It works after about 7 days. Bleeding patterns vary widely from person to person. Many have no bleeding at all. Your tests are negative indicating you are not pregnant
