how does the birth control shot work
Depo-Provera is a type of birth control shot that contains man-made progesterone (pro-JESS-ter-ohn) called medroxyprogesterone acetate. It is given once every 3 months in the arm or buttocks, or in the fat layer under the skin. The shot can be given during the first 5 days of your period. If you have just given birth, you can have the shot right after delivery, before leaving the hospital. This drug can be used by women who want to breast-feed.
