Hello anytime you have unprotected sex, there is a chance for pregnancy, however with the bleeding and the pain, you may want to see a healthcare provider about a possible infection. Also pregnancy is the best possible outcome of having unprotected sex, there are a lot of things ten times worse out there that I can think of. You're young becareful and get checked out as soon you can, if you do not have have health insurance then check your local health department for free clinics that they may have. Don't wait to long to have yourself checked out, because if there is something that is there that needs to be treated the sooner the better. Good Luck!
