First postpartum period

Ok mama talk to me about your first postpartum period. I'm currently in the middle of my first one back and I'm a little concerned because it has been dragging on for a few weeks. I spotted for 2 days back around Jan 3rd thought it could had been implantation bleeding so I waited 3 days and took a test. It was negative. Went on with life then about a week later I spotted for about a day then it stopped so I took 2 more test both neg. TMI WARNING Now I have been spotting all this week nothing heavy at all only when I wipe to I really have anything it is thick slimy very dark blood. Bit the bleeding is hardly noticeable on a panty liner. I know pp periods can be different then pre Pregnacy periods but this is really odd for me. Before I was 7-10 heavy and I mean HEAVY flow like I would bleed through a tampon in an hour on my heavy day . My postpartum bleeding was less than my "normal " period.
