Sooooo A few weeks after my c-section I had stopped my postpartum bleeding, then about a week or two later I had cramping accompanied  with some cramping and bleeding which I assumed to be my period, after it ended I’ve been having this weird smelling discharge and thought maybe it was just leftover lochia or the fact that I haven’t really been paying much attention to that area due to being scared of touching it lol anyways at my 6wk postpartum doctor said everything was fine I’m healing great...... I’m not almost 12 weeks postpartum and still having this wierd discharge although it has now increased and gushes our I’ve gone to the restroom multiple times thinking it’s my period but it’s just this weird smelling vaginal discharge sometimes it’s clear other times it dries in kind of a clear yellow/lights brownish color, I’ve now had some pain/cramping (I assumed my period was coming again), and yesterday I went to pew and wiped and there was just random bright red blood(thought it was my period) but it was gone by the night and is now no longer there and no previous spotting before this(I’m on depo shot not sure if that can cause abnormal bleeding?) and occasionally it hurts to pee here and there not every single time.... I’m making an appointment with my obgyn anyways to get checked but was wondering if anyone ha similar symptoms and what it turned out to be??
