*TMI pic* Pregnancy symptom?!

Okay, so I've been getting this creamy/egg white-ish/watery CM. Yesterday and the day before there was a little bit, but today there's a lot of it!! Almost like I can feel it trying to pour out. Also I've been having dull cramps off and on in my lower stomach and dull backaches. I would think that I'm ovulating but I already did 4 days ago! (I think..) And AF isn't due until Sept 7th. Is this a pregnancy symptom? Or could I be ovulating again?
