I'm 5days late and all negatives HELP!

cece

I'm 5days late from my period, every test I've taken (first response and clear blue) have said I'm not pregnant. But I have extremely sore breasts, food it's just gross, light pink spotting at 4days past my last period. I also have no changes in life style or stress(nothing more then the norm) and no new medication.... this is just beyond weird for me.

Clear blue 1-2days late

First response 5days late

Any ideas Lady's?
