Possibly: Consistent use of the pill is essential to get the best contraceptive effect and skipping pills may allow you to ovulate and get pregnant. It depends on how many days you skipped pills and whether it was in the first 2 weeks or the third week of hormone pills. Continue to take your pills for the rest of the cycle and use other protection until you get your period.
