Seasonique Contraceptive

Seasonique™ (levonorgestrel/ethinyl estradiol) is a contraceptive designed for women. It is a birth control pill that is taken once a day to prevent pregnancy. As a combined oral contraceptive, the medication contains both an estrogen and a progestin.
This drug works to prevent pregnancy primarily by stopping ovulation (the maturation and release of eggs from the ovaries). It also prevents pregnancy in two other, minor ways. Seasonique alters the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus.
In addition, this medicine alters the lining of the uterus (called the endometrium), making it less receptive to an embryo.
Seasonique is an "extended-cycle" oral contraceptive, which means that it provides more time between menstrual periods. With this birth control pill, you will only get your period once every three months (four times a year).
