Probably not: if you have been taking your pills as directed then you are unlikely to be pregnant. If you are worried then take a home pregnancy test. You may be having some breakthrough of your bodies normal cycle through the birth control and may need a pill with a higher estrogen content. See your family doctor or OB/GYN or consult a local doc on HealthTap
