There are various brand of combined hormonal contraceptive pills in the market. Be sure to take the pill every day at the same time. Depending on the the brand, your pills may have 21 or 28 pills. If you have 21 pills, take all the pills for 3 weeks followed by one week without pills or if you have 28 pills, just continue with the non-active pills for one week. Vomiting, diarrhea and certain medication can reduce the effectiveness of the pills. 

A pill is “missed” if you do not take active pills for 24 or more hours after you were supposed to. If this happen, take the pill as soon as you remember, even if you have to take two pills on the same day. You do not need to use other form of contraception. If you missed 2 or more active pills, take the last pill you missed as soon as you remember, even if you have to take two pills on the same day. Throw away the other missed pills. Consider using emergency contraception if you have had unprotected sex in the last five days and do not want to become pregnant. To protect against pregnancy, use other form of contraception (such as condom) until you have taken active pills for 7 days in a row. If there are less than 7 active pills left in the pack after you take the last pill you missed, you can skip the hormone- free break by starting the next pack immediately.
