What happens if you are late taking your birth control?

Answer 1

Taking most BCP late will not have a serious effect on their ability to prevent pregnancy, the exception to this is the progesterone only "mini pills" - being as little as 3 hours late leaves you susceptible to ovulation and pregnancy and must have a reliable form of back up until you have been back on them for 7 days with no mistakes.

If you are on a progesterone only pill and having trouble taking it at the same time daily you should discuss a more reliable form of BC with your health care provider.
