I cant stop worrying I'm pregnant??? help??

Betty

i know I didnt have implantation bleeding and it was probably just some light bleeding after sex, just pink when I wiped and yet I can't stop worrying it was IB. I know I felt it hurt when he was fingering me and I know that probably caused it but I'm still seeing little streaks of pink show up in my underwear? its not blood or anything but little bits of pink? help me calm my mind. I'm on the combo pill and have never missed a dose, just taken it 9 hours late then 7 hours late. i know my chance for pregnancy is like zero but I cant stop worrying!
