POST ABORTION BLEEDING - Should I be worried?

PLEASE READ THIS, I AM SOOO CONCERNED AND I DON'T KNOW WHAT TO DO... :((

I had my abortion done on June 15th. I was only 6 weeks along, so the doctor said I would revocer quickly compared to his typical patient which was about 8-10 weeks. I waited the week that they said I should before I started physical activity. However, I am an incoming freshman in college and I will be playing college basketball, so I immediately began playing the day I was allowed. I was fine. I was a little rusty because I hadn't played for a week, but there was NO bleeding. Weeks have gone by with no bleeding and starting a couple days ago I began bleeding somewhat heavily. I say it is "somewhat heavy" because it is a heavier flow than the bleeding I had immediately folloiwing my abortion... I don't think it's my period... it just doesn't look like period blood. I don't know if I should be worried. I have no cramps. I don't have a fever. I feel fine except I'm concerned about the bleeding.
