Increased CM (TMI) No photo

Anybody experienced increased cm before bfp? AF is due today. Last few days I've had a significant increase in creamy, thick, gooey cm. I've never had so much at this point. Right before AF I do get a slight discharge but then she shows. It feels like she's here but I go to www and it's not her. I feel so wet. So not normal for me. Past week or so I've had weird cramps, sharp pains in my lower belly, back ache, leg ache and highly sensitive nipples too the point of pain. Any one else?
