I had an abortion 2018 october my last and I then got a two months injection. I was suppose togo back on the 3rd of december 2018 but I didnt.. been having unprotected sex since.. and I havent had my periods.. I then started taking the oralcon pill but I missed the first 3 pills meaning I started taking them on the forth day.. 4 days ago I had sex but he didnt come inside me and I have a light brown bloody discharge.. could I be pregnant? I am now on the 24th day of the pil
