Oooookay, so yesterday I woke up and something didn't feel right. Went to the restroom and it looked like I started my cycle when I wiped (bright red). Couple hours later I go to change my tampon and it stopped so I didn't use another. I woke up this morning and it was brown like old blood when I wipe? Mind you no cramping or signs of period like I use to have. I'm 7 wks pp and I stopped bleeding like 3 weeks ago. Plus I EBF, I'm confused lol.
