HELP! Am I pregnant/implantation bleeding

So I had unprotected sex on November 17th and took a Plan B the following day because he wasn’t sure if he was nutted. We had unprotected sex again on 19 November Tuesday. I took another Plan B that night because he wasn’t sure if he got anything inside. On November 29, I started experiencing light bleeding that was pinkish and now is dark red with little clots. I am not supposed to start my period until December 11thand I also wasn't ovulating the days we had unprotected sex.
