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. 92.9% of tests taken by pregnant women were negatives - thus making them false negatives.

    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?
  • 5/59 weeks ago » NamelessAria said:
    This test was surprisingly amazing. I got a faint but clearly there and pink positive on 10DPO with only around 10miu of hCG.

    Followed directions by the book. Test did not work properly. Urine took 5 minutes to begin moving up. Never made it past the Test line. 15 minutes after faint line appears next to T. Assuming evap.

    My go to test. It can take a couple mins for the line to appear. But it's always been spot on accurate for me.

    Mine showed positive within seconds. I was using FRER Digital and those are expensive. Went to these at about the 3rd month TTC. I would say they are accurate. I haven't even missed my period and got a positive already.
