Mucus with blood after ?

Okay so today I had and we used some lubricant and a condom (so yes, it was safe ) but basically I just forced it in and we went from there. Today, around four hours later, I go to the restroom and some mucus looking goo comes out and its a little spotted with blood. Is that normal? Was it just injury from force and the unusualness of not having or should i see a doctor?
