Infection after birth?

If I had an infection I would be running a fever right? I have taken my temp two days in a row and it is 98.5, not a fever. I had a urinary infection after the birth from the catheter and I got treated early on because I knew something was not right. I am now four weeks post partum and I am no longer bleeding but I had some wierd discharge that was a strange color. I am not sure if it was this color because the bleeding is stopping but still a little there? Should I be worried about it or no sense I don't have a fever, chills, cramps, or anything? I have some pains occasionally but they are generally in my rib area probably from everything going back to normal.
