Discharge after postpartum

Hi, anyone has ever had small clot like brown discharge (only when pee-ing & its very little) after months of giving birth? Should I be concern? Keep on having on & off similar discharge after almost 5 months of labor (via csect & not bf) Menstruation has went back normal since the 2nd month of labor. The brown disharge, however only starts for the past 2 weeks. Not on a daily basis though but on the days its there, it will be appear like 2-3 times when i pee.
