TMI picture, but NEED help! Is this a blood clot?

I am 6w and 6d pregnant. I had some brown bleeding earlier in the week, which I assumed to be implantation bleeding and the placenta attaching. This morning I had different blood. Is this considered clotting? I'm so sorry about the gross picture.. should I go to the hospital? I called my nurse and they want to know if I'm clotting. This is my second pregnancy and I've never had any kind of spotting or anything before. Thanks ladies.
