4 Days Past Ovulation

Note: There are only 11 tests recorded for this day past ovulation for this brand.
For this reason, the statistics may not be entirely accurate.

Total Positive: 0% - Total Negative: 100%

Result Percentage Number of Tests

Standard Positive00 tests
Strong Positive00 tests
Negative 90.9%10 tests
Evap9.1%1 tests
Total Number of Tests Included In The Data11 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. To avoid unnecessary disappointment you should try and wait as long as possible before testing.

    I am NOT a fan of these tests... They work, and give accurate results, however they are veryyy slow, it takes the full 3 minutes for anything to show and about 10 minutes before the line is at its darkest. It is a very nerve wracking test!
