USING COMBINED HORMONAL BIRTH CONTROL PILLS
What are Combined Hormonal Birth Control Pills?
Combined birth control pills are oral pills taken daily that contain 2 hormones (estrogen and progestin). They prevent pregnancy by stopping the release of an egg (ovulation), thickening the cervical fluid, and changing the lining of the uterus.
How effective are Combined Hormonal Birth Control Pills?
The pill is a very effective method of birth control. The pill is about 93% effective at preventing pregnancy in typical use, which means that around 7 out of 100 people who use it as their only form of birth control will get pregnant in one year. With consistent and correct use as described in this fact sheet, it can be over 99% effective.

When do I start my pills and when are they effective?
It is recommended you start your pill right away. The pill is effective in preventing pregnancy after one week of use, so you need to use a backup method of birth control such as condoms, or not have sex for 7 days. You do not have to wait for your period to start, but if you happen to start on the first day of your period you don’t need to use a backup method as the pill is considered effective immediately.
How do I take the Combined Birth Control Pill?
Most birth control pills are packaged based on a 28-day cycle. Your pill pack contains at least 21 hormonal pills and you must take all of these pills in a row (one a day at around the same time). After you have taken all the hormonal pills in the pack you can:
- take the sugar/placebo pills (if your pack has any) OR
- take a short pill-free break of no more than 7 days, OR
- go straight into another pack with no break or sugar pills
In order to be protected from pregnancy for the whole month, you must be sure to start your next pill pack on time and never go longer than 7 days without a hormonal pill. Periods that occur while using the combined hormonal pill are a result of taking a break from hormones. Taking no hormone break (or a shorter than 7-day break) to lighten or skip periods is safe and may make your pill more effective.
What if I miss pills or take them late?
