It is usually given in the arm or rear, delivering a high level of progesterone into the body. It stops the ovaries from releasing eggs. It thickens the cervical mucus and changes the uterine lining, making it harder for sperm to enter or survive in the uterus.

hese changes prevent fertilization. This product is a very private form of birth control because it cannot be seen on the body and requires no home supplies. It does, however, require a clinic appointment every 3 months.

If you are more than a week late for your shot, use a backup method of birth control for the next two weeks. If you are more than a week late and you have had unprotected sex since your last shot, consider taking a pregnancy test before receiving the next dose.
