For pregnant women, this brand starts to give positive results for more than 80% by 12 days past ovulation. This means that at least 4 out of 5 pregnant women will get a positive result on 12 dpo or later.


By 14 days past ovulation this brand gives a 'standard' test result. Which means the test result is easily distinguished as a positive result (usually nearly as dark or as dark as the control line)

Evaporation lines

Of all tests recorded using this brand, 1.6% were reported as evaporation lines. This mean around 1 in every 63 test results was an evaporation line. This is considered medium risk.

Only pregnancy test results reported by pregnant women are included. Therefore any negative results are false negatives.

A false negative result is when a pregnancy test indicates that you are not pregnant but you actually are. False negatives usually occur because there is not enough hCG in your system to be picked up by the pregnancy test. This can be caused by the test being taken too early, test sensitivity, diluted urine or failure to follow test instructions. To avoid inaccurate results you should try to wait as long as possible before testing.

These have worked great for me. Stark white when negative and clear colored lines starting at 8 dpo.

I used to love these tests but after seeing other users photos, and my own experience from this cycle, I'll be changing brands. I recieved 3 vvvvf evaps, 2 of those 3 already had lines on the test strip. No more cheap tests for me

I have had two confirmed false positives in the last week, one day before and one week after AF. Hcg blood draw a week after my period started says definitely -, but wondfo was + THE SAME DAY.
