Cramping 9-10 dpo

I'm 10 dpo and have been cramping yesterday and today. Of course my mind says, "that's a good sign, you're pregnant!" but I keep telling it to be quiet because I don't want to get my hopes up. I don't get cramps very often and when I do it's only during AF...I'm not supposed to start til Saturday or Sunday. 
What do you ladies think? Is this something I should be hopeful over or not so much?
