For the past few days I've been bleeding a darker almost brown blood. And last night I started to bleed bright red blood, and got severe abdonimal pain, cramping, back pain, feverishwith hot flashes and chills, I couldn't stand up straight, and when I tried to use a tampon it hurt extremely bd and mybody woud push it out, so I went back to using pads. I finally fell asleep andwoke around 2 am feeling a lot of pressure like I hadto use the restroom really badly. I tried to pee but I just bled I felt like I had to push bu didn't and whenthefeeling started to pass I stood up and as I stoodup, I passed a fairly large bloody piece of tissue I guess you would say, it looked sort of like abloody clar mucus sack with something white in it. I totally freaked out, so I didn't get any closer to examin it. But I've had 4 children and the first thing It looked like to me was the beginning of a baby, could this have been a miscarrriage? And I just didn't know I was pregnant?
