NOTE: Positive pregnancy test results are so highly uncommon for any day prior to 6 days past ovulation that they really should not be considered in this data - Any positive test result this early is usually due to a miscalculation of when ovulation occured and thus does not accurately represent the true day past ovulation. Most home pregnancy tests measure the amount of hCG (human chorionic gonadotropin) in the urine, it is only once the fertilized egg implants (around 6-12 days after ovulation), that the developing placenta begins producing hCG.

    showed stark BFN after IC showed faint pos. Although the blurred line deckdolly refers to is the horizontal strip *behind* the test strip and will always show. i only found this out because i took it apart after my unexpected BFN! not as good as i was told they were.
