Mucus and bloody discharge - help!!!

My boyfriend and I have been together 2 years, and about a week ago, we had sex without a condom, and he came inside me. I was on the 2nd day of my fertile period, but inhibitions were down and although we use withdrawal, he came inside me. Now, a week later, I'm experiencing some cramping with my cervical mucus tinged pink (light blood, maybe?) and when I just went to go pee, I had ropes of bloody (bright red blood) mucus (the texture of egg whites, but bloody) on my thighs. Anybody have any insight on what may be causing this?!?
