help!! I'm scared!!!

Girls I'm not due for my period for five more days. I never start my period early, if anything I'm always late. Anyways 10 days ago me and my bf had unprotected sex twice. He never came in me, but he never peed or anything in between the two times. If tht makes any sense. And tht day tht we had sex according to this app I had a 33% chance pregnancy. Well today when I wiped I got this. Am I pregnant? Like is this the implantation bleeding? I am only seventeen and have never been pregnant before so TBH u girls are the only ones I can go to for answers. My parents are very religious and would be very upset if I was pregnant so I can't say anything. Can anyone help me? Please I need answers asap
