Faint line then negative- Clinicgaurd test


I got what I thought was a faint line positive Sunday on a dollar general cheapie. Ever since ive been using theclinicgaurd cheapie and get absolutely no line at all. Anyone else experience this? It's so confusing 😔😔😔 Af is due tomorrow and I have felt pregnant! Even have had very light pink spotting Friday, Saturday and yesterday which I never have before a period!
