Have had good experiences with the Ovu- tests of AIDE. While standing in the instructions for the second line should be as strong as the Line of Control, which she was not with me, but it worked. As I have already tested a few days earlier and knew how the test I was there looked (pale until no sign of the second line) I on the date certain that this is the LH surge. The line was a little lighter and not very pronounced, but otherwise clearly. Granted, I have the test not entirely trusted and, therefore still carried out a Clearblue digital ovulation test after allegedly positive results at the beginning. This then was a positive effect :), so hats voted.
So if such a test with a little familiar, will look when it is positive. Just not on the stiffen the test line must have the same intensity of color as the control line.
