Light brown discharge and slight pain 3 months pp

ericamanuela

I had my son 11 weeks ago. Yesterday and today I've had very little light brown discharge and some lower right abdominal pain, almost like pressure pain. I breastfeed and I haven't gotten my period yet, only times where I've had this same brownish discharge but it never turned into a period. Any idea what this could be? Possibly old pp bleeding but why the slight pains?
