AF due August 6-8

Hi everyone. Af is due August 6-8. Been having slight cramping since over the weekend but nothing major. Less than period cramps. I feel very moist below, thinking she may show her ugly face so I go to the bathroom and nothing. But I'm also 2-4 days away. Glow says to hold off til tomorrow for testing so I am. Glow also said Thursday being my highest percentage and I has sex that Saturday. Is there a good possibility tht i could be Preggo? I'm am TTC #3.
