Period after Birth Control

I was on the deposit shot for 2 1/2 years. My last shot was last August. I have not had it injected since and still have not had a period. Is there anything I should be worried about?

Most women have some changes in their menstrual periods while using Depo shot, including irregular and unpredictable bleeding or spotting, an increase or decrease in menstrual bleeding, or no bleeding at all. Consult doctor, you may need birth control pill to start your regular menses.
