Spotting

I am three months post op, uterus, tubes cervix and one ovary. I have had no spotting since leaving the hospital other than I think once I did too much earlier on...about 2 weeks ago I had some minor pink when I wiped (once) but since then I have been having mild brown spotting when I wipe?? Anyone know why? And I get mild cramps...I was in to the walk in clinic last week witha bladder infection but forgot to mention the spotting.

I'm six weeks post op and have had pretty heavy discharge, myself. It's more of a mustard color (sorry to be gross and graphic) but no blood. I read on here that the internal stitches can start coming out but I don't see stitches, just mucus-y discharge. Anyone know what this is?
