I actually bought these tests to know my ovulation period because my cycle is irregular. I followed the instructions to the letter (I found the leaflet in French on the Internet) but tests have been negative tjr. During this time I used these tests and I went to see my gynecologist and I told him that I thought did not ovulate (after testing). He made me an immediate echo and saw on the screen that I had ovulated (the day before or the day before) hence my dissatisfaction with the tests. For me, this test did not satisfy me.
