Post-Coital Spotting: Causes, Concerns, and When to See a Doctor

Question
Hi!  I am 18 years old, and around 3 days ago while having sex, the condom fell off inside of me, so we immediatly stopped and took it out.  Right after, I began having really bad stomach / uterus pains (Could have been from trying a new position..) and it took 2.5 days for them to go away, now on the third day, Ive noticed a light spotting when I wipe myself when I go to the bathroom.  It's not like the blood from my period, either, and this has never happened before... any idea what could be wrong?

Answer
cassie;

well this could be from sexual active[somewhat rough]and a different position.
it sounds like maybe you have bruised your insides. give it some time to go away[a few days] if it still giving you problems,then maybe its best to see your doctor;
