In fact, being even 12 hours late in taking your birth control pill increases your chances of getting pregnant. If you miss any of the first 21 pills in your pack you need to use an alternate birth control method, such as a condom, for the next seven days. Less Than 24 Hours If you are less than 24 hours late taking your birth control pill, take your pill immediately and then resume your regular pill schedule. However, if you remember to take your pill the next day and realize you forgot it the day before, take both pills at the same time. Never take more than two birth control pills in one day, unless directed to do so by your health care provider. More Than 24 Hours If it's been over 24 hours since you took your last birth control pill, take the last pill you missed and then take the next pill as scheduled. If you've missed more than one pill, throw away those you missed and take the rest of your oral contraceptive package as scheduled. During the Third Week Should you forget to take a birth control pill during the third week of your pack, finish all of the oral contraceptives in your pack and skip the last seven (non-hormonal) pills. Instead of taking those last seven pills, immediately begin a new birth control pill pack, understanding that you may not have another period until you are finished with this new package. Use another method of birth control until you have taken 7 pills from the new oral contraceptive package. Using Alternative Methods As mentioned above, you should use a condom for seven days after you've missed a pill. And if you've missed two or more pills in one cycle, you should use a condom for the rest of your cycle, until you get yourself back on track. Using a condom and spermicide with a diaphragm or cervical cap during your fertile period has been shown to result in almost 100% contraceptive success. You can also call your physician and ask for an emergency contraceptive if you realize you've had unprotected sex. You have 72-120 hours after unprotected sex for emergency contraceptives to be effective. Was this page helpful? Thanks for your feedback!
