Hi, I woke up and had a fleshy looking tissue blood clot. It was skinny and kabout 2 inches long, it look like it had veins in it. Later on that day I took a pregnancy test and it was positive so I took a blood test and it was positive also. My last period was nov 25 2012. What could this be??

You post is confusing. I suggest you go to the doctor and get checked over. If you had a miscarriage, immediately after the test would still read positive. There would not have been time for your body to adjust to the miscarriage.

On the other hand, the 'material' you thought you saw, would not have contained veins, if a miscarriage it would have been a large blood clot and a bit of tissue; taking into consideration the time you could have been pregnant from, say, late November.

Go to the doctor.
