miscarriage with almost no bleeding

Brittany
This evening had to of been one of the most bizarre evenings of my life. I am 24 weeks pp and was not trying to conceive with baby number 2. Over the last two weeks I have been cramping a little but nothing serious. This evening while I was using the restroom this came out while I wiped, I know TMI, but it did. I don't know what to think or do or say, any and all advice appreciated.
