AF three days late

Jessica • I am a mother of two beautiful girls and a wife to a goofy fun loving husband 👨‍👩‍👧‍👧
My AF was due 8/3 and it hasn't come. I have been feeling symptoms of pregnancy for a week now, and I took a test this morning and it was negative. Is it possible to still be pregnant? I did a blue dye test. Im going to wait a few more days to test again if AF hasn't come. Im on cycle day 39!
