Miscarriage?

This is my 3rd pregnancy, I am 6w3d. I started with a bad cold last night, did not take anything, have been laying around all day.i got up awhile ago and had a pretty hard cramp in my lower abdomen, often have round ligament pain n thought nothing of it. Just now went to the bathroom and there was blood when I wiped, and when I got up there was a little bit of bloody tissue or blood clot in the toilet. Am laying down again and have a consistent sharpish pain in my lower abdomen. I have never miscarried before that I'm aware of, do yall think I am or just did. I've never had any spotting or bleeding of any kind while pregnant so I don't know how to classify this
