i have been taking birth control for a few months, i had missed a few pills in the begining on my new pack because i could not get my pack on time, i doubled up and then a week later had been missing pills becuase of work to take them on time. i was not worried because me and my boyfriend had broken up. i had been doubling up and i dont know if i was back on track when we had sex, but the night we had sex i also missed a pill again and had not realized it. i doubled up the next day. then i began to have dark bleeding, but it was very light and that has been going on for a week, but i am supposed to get my period in a few days and i have been continuing to take the pills ontime now, but the bleeding has not stopped. i havent taken a pregnancy test and i am wondering if i should. i also got some pain in my stomach and my boobs are sore. am i pregnant?
