Pregnancy is a possibility but unlikely if you have been taking your pills correctly (at the same time everyday). The only way to be certain that you are not pregnant is to take a pregnancy test. Occasionally, for one reason or another, women experience a change in their periods while on birth control. Sometimes, a simple pill change solves the problem. Menstrual changes can also occur for other reasons though. Contact the medical provider who prescribed your pill and describe your last two periods. They may want to perform some tests and/or recommend a pill change.
