Hello! I bought the ClearBlue Ovulation Predictor Kit. Used it twice (this month being the 2nd). Cannot comment on the effectiveness coz last month did not conceive and this month is still waiting (AF is due this Sat but I think most likely not preg coz no symptoms at all )
But I think it's useful and worth buying esp if your cycles are irregular or if not sure when ovulation will happen. At least you have an idea when to "work" extra hard.
