Not sure what's going on

So my period is 3-4 days late today and about 2 days before I was supposed to get my period I started getting lots of EWCM. I shouldn't be ovulating because I charted temps and took ovulation tests and did ovulate around day 14 or so. I took a pregnancy test today and it was negative. I've also been super tired and nauseated/dizzy lately. Anyone else experience this and did you end up with a bfp or bfn?
