Total Number of Tests Included In The Data8 Tests

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.

Interpretation of Data

Based on these statistics, if you are pregnant and use a First Signal pregnancy test on 4 days past ovulation you are most likely to get a Negative test result. 100% of tests taken by pregnant women were negatives - thus making them false negatives. A false negative result is when a pregnancy test indicates that you are not pregnant but you actually are.

    I used this all through my 2ww. I didn't get a single evap. The day I got my bfp it was clear and dark as day and within about a minute. I confirmed with a digi the next day. Can't beat them!
