miscarriage? warning TMI

Angela
Hi has anyone going be through a miscarriage? I'm wondering if this is happening to me. I started lightly spotting on the day I should have started my period and after having multiple pregnancy symptoms. I had taken a Test but it was negative. I spotted for two full days then yesterday I started actually bleeding like a normal period. I check my cervix and typically on my period when it is low hard and open. It has been high soft and slightly open. Today I was using the restroom and I was bleeding so much it got everywhere so I got into the shower. I reached down so I could clean myself and I felt this large clump of something coming out that was dry. Felt like a damp cloth coming out. I rinsed it off with water and when it feel it looked more clear than bloody and was slimy. Has anyone gone through this?
