T M I (Image Included) 7 DPO

Jamie
Hi! 
I need help. I'm 7 DPO, AF due 5/23. I have all the symptoms of PMS (except dizziness and nausea which are not typical for me but not out of the ordinary for some people). For the past 3 days I've had more CM than usual, especially for an impending period. It started off lotion-like and for the entire day I've been getting little globs of faint yellow mucousy CM. Has anyone had this before a BFP? I've tested but it's negative of course. 🙂
