Total Number of Tests Included In The Data3 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 e.p.t. Certainty Digital 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. To avoid unnecessary disappointment you should try and wait as long as possible before testing.

    It doesn't get clearer than "Pregnant" on the screen! Got my BFP at 12 DPO. Then tested with clearblue digital with weeks estimator and got another positive. Super happy!

    Got a squinter on an IC (supposedly 20 miu sensitivity) at 9 DPO and confirmed with this digital. I'd say it's much more sensitive than the 50 miu the description states.

    Tested at 11 DPO and got my positive! That seems like a good sensitivity :)
