My doctor did not tell me how long to expect bleeding post d&c and I am starting to get concerned.

I got my d&c on the 23rd of june (13 days ago) and am still bleeding. it is red, going through about one-two liners a day. I had to go into the doctors on the 27th because of immense pain where they diagnosed me with an infection. I end the prescription tomorrow and am wondering when to expect the bleeding to stop or when I should contact them again...? Any advice/thoughts?
