Unfortunately I can not recommend that you have delivered to me no reliable results this test. According to the ovulation test I had not ovulate in three months. According to the tests by Rossmann and the blood test, however, the gynecologist already. I had chosen this test as a cheaper alternative to the Rossmann tests. As this but nothing anzeigten (who by Rossmann imm month earlier displayed), I have used both test once parallel. Result AIDE negative and positive Rossmann (ovulation available). Was made the same way in the month as the blood test in FA, and can be 100% trusted.
