Fertility and Conception —>

Timing is everything

About a week before ovulation, your body begins giving signs that you are beginning to be fertile. OvaCue detects these signs up to 7 days before ovulation. Having advance notice gives you a cushion of confidence, not to mention ample time to make time in your calendar and be emotionally and practically ready to “make it happen.”

But advance notice is only half the equation. Since the window for successful fertilization can be as short as a day or less, you also need accurate prediction as the time of ovulation draws close. Some fertility monitors give lengthy notice, but also give “false positives” eight or more days in advance and may continue giving false positives even after ovulation has occurred.

Since you cannot conceive after you have ovulated, successfully timing conception depends on the accuracy of your fertility monitor. Only the OvaCue Fertility Monitor gives you sufficient notice with virtually no false positive readings--98% accurate in NIH-supported testing.
