Implantation bleeding?? Help

I've been reading all kinds of things on the Internet today. I am 9 days post ovulation today. I woke up to a light pink discharge this morning. Throughout the day it's progressively gotten heavier with intermittent cramping. Some small clots were noticed when I got home. Any input? Some websites say it could still be implantation bleeding some say no way that it is an early period. Any input would be helpful!
