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.
Birth control implants are devices that go under a woman's skin. They release a hormone that prevents pregnancy.
Two similar implants available in the U.S. are Implanon and Nexplanon, which is gradually replacing Implanon.
Each implant is a plastic rod about the size of a matchstick. The rods contain a form of the hormone progesterone called etonogestrel.
