Are you supposed to get creamy white CM befor AF?

I just took a shower and checked my CM and it was creamy white like lotion. Sorry for TMI.. Are you supposed to get this before your AF arrives?? Anyone know?? I'm almost 5 days late from my AF and have sore boobs and swollen, been fatuiged and had mild cramping on and off. Just wondering if the creamy white CM could be a prego symtom??
