what's this?

I am 11/12 DPO and TTC. I normally "dry up" after O (no cm or VERY little). I'm cramping like I'm gonna start AF which is due in 4 days. Then I had this CM come out. I know it's normal to have CM but at the point I normal don't have any much less THIS much. Any ideas?
Also - I've tested negative thus far. I had severe cramping and bloating 2DPO - 6/7 DPO. 
(CM is on tp btw)
