Progestin-only Pill

The POP changes the mucus in the cervix making it harder for sperm to enter the uterus, prevents the ovaries from releasing an egg each month (ovulation), and changes the lining of the uterus making it difficult for an egg to attach itself.

Anyone seeking a reliable and reversible method of birth control. The POP may be a good option for an individual who is unable to take estrogen or someone who is breastfeeding. The POP may also be a good option for people who experience migraine headaches or are over the age of 35 and smoke cigarettes.

Take one tablet daily. It is important to take your pill at the same time each day to avoid pregnancy. Try to take your POP with a scheduled activity such as a shower or breakfast. The POP is only available in a 28-day pack; take one pill every day for 28 days. Start a new pack of pills after completing the previous pack.

For the first seven days when you begin the POP, your body is adjusting to the hormones and you are at risk of pregnancy. Use a backup method of birth control such as condoms during the first week of taking POP.
