Cm 2 days before period??

Does anyone else get 'dry' right before they start their periods?? I am always at my driest right before I start. Rather it's sex, or even just any kind of cervical mucus, I am dry about the last 5 days before I start my period. But lately I've noticed an odorless, thin, almost watery discharge, and I get extremely wet during sex... does anyone else experience this? Or is it normal?
