Too soon?

Kortney • Don`t go alone, it`s dangerous.
Ive been feeling extremely sick now for about a week. My spouse and I had intercourse on the 23rd (my peak of ovulation 27% chance of pregnancy) and on the 26th (my last ovulation date, 8% chance) The doctors always have me take a pregnancy test when I go. My AF is expected in 7 days, could it show up this early ?
