The mini-pills, unlike most birth control pills, have only one kind of hormone progesterone.
Every pill is a birth control pill.
It is very important to take a pill every day, preferably at the same time each day. Start your next pack even if you are still bleeding or have not started bleeding. These pills are less effective than regular combination birth control pills. We want to make sure that no problems have developed while you have been taking the pill. Call the clinic for information, but DO NOT stop taking the mini-pills.
