Missing one or more pills by 24 hours or more does decrease the effectiveness of the pill. When you miss pills, it changes your hormone levels , increasing the likelihood of ovulation. However, you did make the pills up so that helps. Withdrawal is not an effective method of birth control as sperm can be present in pre-ejaculatory fluid, but at least your partner did not ejaculate inside the vagina.
Missing pills can cause menstrual irregularities so don’t be surprised if you start bleeding or spotting before your period is due. Your next period may be different from what it normally is like. However, if you miss your next period, take a pregnancy test. If you frequently miss pills, you may want to consider switching to another method of birth control. If you would like more information about your contraceptive options, please contact one of our offices.
