Vaginal contraceptive film is a paper-thin film that has a spermicide in it. A woman can place it in her vagina on or near the cervix (the entrance to the uterus), where the film dissolves in seconds. The spermicide in it works for about an hour.
You should wait at least 15 minutes after inserting the film before having sex. And you must use a new film each time you have intercourse.
Depo-Provera is a contraceptive method for women. It’s made of a hormone similar to progesterone.
It's a shot that a doctor gives you in the arm or buttocks. Each shot works for up to 12 to 14 weeks, but you must get the injection once every 12 weeks to get its full protection.
