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.

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. 87.5% of tests taken by pregnant women were negatives - thus making them false negatives.

    Unlike many of the other tests, there's no questioning the result. I got results that made me think I was pregnant, but with this test, its a clear negative.

    These tests are cheap and very reliable. I got my first positive on them at 15DPO with a very very faint line. They're only $.88 each, so they're great for people (like me) who are addicted to POAS. lol

    I got an extremely faint line. It says not to rely on any results after 10 minutes, but I checked back and the line that I thought wasn't even there was there. Is that a BFN?

    This test was surprisingly amazing. I got a faint but clearly there and pink positive on 10DPO with only around 10miu of hCG.
