2 days late bfn

Okay so now I am 2 days late with lots of ewcm. No cramps or anything and my periods usually start with severe cramping the day before and do not stop until the maybe the day after my period starts. I have had a lot of nausea and am super fatigued. I also want to say that I never have ewcm, not even during my most fertile times. This morning it was tinged slightly yellow and then it was clear again. Oh I also tested the morning my period should have arrived and it was negative. What do you guys think?
