What To Do If You Miss a Pill
If you miss one active pill...
Take the pill as soon as you remember that you forgot to take it and take your next pill at the usual time.
Two active pills in a row during the first two weeks of the pack...
Take two pills when you remember and take two again the next day. Take one pill every day after that until the pack is finished. It is important that you use another backup method of birth control for seven days after you missed your pills because the possibility of getting pregnant increases when you miss pills.
Two active pills during the third week, or three or more pills in a row during the first three weeks...
What you do depends on whether you are a Sunday-starter or a first day starter:
- Sunday Starters: Keep taking a pill every day until Sunday. Throw away the rest of the pack and start a new one on that same day.
- First Day Starters: You should throw away the rest of the pack and start a new pack on that same day.
- Everyone should also: Use a backup method of birth control for the next seven days. Also, chances are that you will not get your period this month so don't worry. If you miss more than one period you should consult your doctor.
- IF you are still confused: You should continue to take your birth control pill regularly and use another method of birth control until you get a chance to talk to your doctor.
Effectiveness
The combination pill has a failure rate of .1% when women are perfect users. This means that one woman out of 1000 will become pregnant in one year if the pill is used correctly. The failure rate among typical users is 5%, meaning that five women out of 100 will become pregnant within one year in typical conditions. Obviously, it is important to use this method as perfectly as possible.
