I purchased these and was very satisfied with the ovulation tests, however the pregnancy tests were very unreliable. At 5DPO I was getting faint positives and amazed because it was so early!! However the tests never got darker over the days and always tested negative with a First Response test. Even today, I got a faint positive then looked down only to notice I started my period.It was so confusing and heart wrenching to get the joy of the faint line only to have it be false.I WOULD recommend the ovulation tests and WOULD NOT recommend the pregnancy tests.
