Light Period, Spotting, Slimy Blood When Wiped. Pregnant?

Hi, I was wondering....if I had a really long cycle this month (for whatever reason) and didn't get a period until CD45 could there still be a chance I am pregnant? I am asking because even though it is redish. It is lighter than a "normal" period for me. It started yesterday and all day I was spotting, not a normal 1st day for me. Today (2nd day), I am bleeding but normally my 2nd day is very heavy, and it's not. Not even wetting the pad much, but there is blood when I wipe and is very slimy (sorry tmi). Just curious.
