Hello. Let me start with some info about me. I'm 32, 13 years ago I had a miscarriage. Since then I've had two children. I have missed my last three periods in a row, and have a lot of the typical signs of pregnancy. sore breast, nuesuea, hot flashes, very emotional. About a week ago I started cramping then three days ago I started bleeding heavily, I have had severe back on my left side and stabbing abdominal pain on my left side. I have passed two blood clots the size of a golf ball and have gray matter mixed in with the blood. I had my tubes tied when my last child was born 10 years ago. Could I have be having a miscarriage or tubal pregnancy?
