I am a 19 year old female and I have been on microgestin for almost a year now. Last month my period came a week early but was unusually heavy and clotty. That pack I had taken a few pills late but never missed a whole day 24 hours. After describing my situation to my mom she thinks I may have gotten pregnant and had an early miscarriage. I didn't get my regular period the next week. Could I have been pregnant? If I continued into my next pack am I protected from pregnancy if I take the pills correctly every day?
