When do you have to get the depo injection I got the depo a week before my time do you think i will get my peraits?

The Depo-Provera injection is effective in preventing pregnancy for about 12 weeks, and many women do not experience their periods while on it. Since you received the injection a week before your expected period, it's possible that your menstrual cycle may be disrupted. Some women may have lighter periods or none at all while using Depo. If you have concerns about your cycle or potential side effects, it's best to consult with your healthcare provider.
