I've been on ortho evra for 2 and a half years I think and I took it off today so I can get my period sometime this week in a few days. I had sex with my boyfriend of four years and he came in me! I was pissed! Is the birth control still in my body system? I hope the birth control is still in my body system so I ding get pregnant. If anything please pray for me.
