These tests do NOT work as advertised & will only increase your anxiety.

I bought these tests for the same reason everyone else does: to confirm whether my progesterone levels were high enough to show I had ovulated. I tested for 4-5 days, including the days when the progesterone levels should've been at their highest. The second pink like NEVER fully went away. As other reviewers have noted, this is a common occurrence with these tests. The problem is that the test instructions are VERY clear that ANY hint of a second pink line is a negative result, meaning your progesterone levels are too low to indicate you have ovulated. Well, the same day as the last negative test, I went to get bloodwork done--and that bloodwork confirmed my progesterone levels were high enough that I had ovulated, AND high enough that, according to the literature included with the at-home tests, I should have received a positive result on those at-home tests.
Needless to say, I will be getting my money back. Too bad I can't get my $30 copay back as well. There is NO point in using these "back-up" tests to confirm ovulation given that you have to get a blood test as backup to confirm the accuracy of the results, only to find out they are not accurate at all. Ridiculous. These tests are not ready for sale to the public and the manufacturer needs to go back to the drawing board (or modify their test literature, if a faint second line CAN in fact mean the result is positive under at least some circumstances). To me, this is borderline consumer fraud.
