Normal or miscarriage?

AF showed up right on time, but just about everything with this period has been different for me. This is the second clump of tissue I have passed today, and this morning when I wiped it was a bunch of really small clots. Does it look normal or is it possibly an early miscarriage? When I wiped away some of the blood some of it was stringy but it was mostly solid and like stretchy. It was like a white/gray kind of clear color.
