I been taking the pill since Nov 8. I'm a little nervous because me and my fiancee have been sexual active constantly, over the course of week's. I got my first period on December2nd , my 3day cycle ended and we continued to have intercourse i know that usually after a females period she can easily get pregnant. I was wondering if the pill is still in full infect or if I'm pregnant. We don't want to have a child this early. I've also been throwing up and having really bad headaches i can't sleep for the most part. Can anybody relate?
