It is administered starting within the first five days of your period, then every 12 weeks thereafter. Working similar to a birth-control pill, Depo-Provera has the hormone progestin, which changes the lining of the uterus, making it difficult for sperm to fertilize an egg. In the weeks between shots, you do not have to use other contraceptive methods. It is 99% effective in preventing pregnancy.

What Is The Birth Control Shot? How Does Depo-Provera Work? The shot is a progestin form of birth control and it works by preventing eggs from being released from the ovaries, as well making cervical mucous thicker (which helps prevent sperm from reaching a woman’s eggs). If you get the shot within a week of your period’s start, Depo-Provera starts working right away. If you don’t get it during that time in your menstrual cycle, using a back-up form of birth control is recommended for that week after the shot. While some of you may find shots a little scary, but let’s just say that there’s nothing scary about the effectiveness of the Depo-Provera shot. It is 99% effective at preventing pregnancy. However, like the pill and IUDs, the Depo shot does not protect you from STDs (so again, as always, wear a condom !).
