34cd- No AF- BFN

AF was due on 4/9, I've had sore heavy breasts for 8 days, feeling super bloated, and get that butterfly feeling in my stomach. I also had the paste like CM for awhile but in the past 2 days my CM has been dry. I tested yesterday evening on a FRER and only saw one pink line (BFN).   usually have a regular 28 day cycle so now I'm confused about what's happening to my body.
