There are two types of oral contraceptive pills, one contains estrogen and progesterone, the other contains progesterone only. Ortho Evra, a weekly patch you place on your skin, contains estrogen and progesterone and works in the same way as oral contraceptives. NuvaRing, another estrogen and progesterone based contraceptive, is similar to Ortho Evra but it is a ring that is placed inside the vagina once a month. Depo-Provera is a long-lasting synthetic hormone similar to progesterone. It is designed to last for three months but it may last even longer. It can take almost a year before Depo-Provera is completely out of your system. The Mirena IUD is a T-shaped plastic device that releases a synthetic form of progesterone. It is inserted into the uterus and can prevent pregnancy for up to five years.
