Description
Birth control shot is an injection you receive to prevent you from getting pregnant. It is also known as Depo, Depo-Provera, and has progestin,a synthetic version of progesterone. This helps prevent ovulation (meaning prevents the release of an egg from the ovary so cannot have sperm fertilize the egg to create pregnancy). It also works to thicken cervical mucus, making it harder for sperm to pass through the cervix into the uterus.

Most common side effects are breakthrough bleeding (spotting, more frequent bleeding) or skipping your periods (which is okay if the medication is causing this!)
