pms or possibly preggy?

Heather
I have been cramping for 10+days now.. I never cramp unless I'm ovulating or right before AF. I have had sore breast for a week and the cramps have been dull achey feeling. I've taken 2 test last week that were negative but maybe I tested too early? I'm due for AF tomorrow but also usually spot a day or 2 before and I haven't had that yet although I have felt like I was going to start early this weekend but all I get is just very watery and sometimes egg white CM? Anyone else had any of these symptoms?
