I started birth control ( Tarina Fe 1/20) on January 8, and had unprotected sex January 16, he finished inside me, I waited the seven days before having unprotected sex and didn't have sex during the week I started birth control. I had my period on January 17, and I continue to have discharge after my period. I'm still taking the pill daily at 9:30 every day, I haven't missed a day. Is there a possibility that I am pregnant? Or am I overreacting?
