6 days is too early to test, your not out until your period arrives :) wait a few more days and retest. If egg implants at 10 days post ovulation it will take a few days for pregnancy hormone to be at a detectable level in ur urine x
Im due on in 6 days do wondering if its about now. I done a test that states can be done 6 days earlier and was negative. But hoping i still could be preggers!
5-10 days after ovulation I think.
