It was not clear from your question whether you are currently using birth control pills or whether you recently stopped using them. If you are currently using them, the contraceptive effect of birth control pills doesn’t just wear off (as long as you are using them correctly – taking them at the same time everyday). However, your body may have changed and now needs a different type of pill to maintain regular menstrual cycles. If this is the case, contact the medical provider who prescribed your pill and describe your menstrual irregularities.
If you recently stopped the pill, the contraceptive effect wears off almost immediately in most individuals. You may ovulate the very next month after stopping. Once you stop using the pill, your menstrual cycles almost always revert to the way they were before you used the pill.
