I have been having a discharge a few days after I had my d&c which was on May 9th.. And wondering what it could possibly be.. I've been tested for all STDs and everything.. so what could it be.

Bleeding, of course, and discharge are to be expected and as long as the discharge does not have a foul odor don't worry about it. A foul odor would indicate an infection.

Agree, what color is the discharge ? Is there a smell. Many women have a natural discharge often. So without more info, can not tell if there is a issue or not
