Find your Most Fertile Days

The KNOWHEN® Ovulation Test tracks your ovulation using only a drop of your saliva. It identifies your five (5) most fertile days and the best days in your ovulation cycle if you’re trying to conceive.

Ovulation can be detected by various signs not readily discernible by anyone other than the woman experiencing them. Women nearing ovulation experience changes in their cervix and the mucus it produces along with their basal body temperature.

How to use

Test daily, including during menstruation, to track consistent patterns over time. It’s important to maintain daily testing for several months to gain reliable insights. Limit testing to once per day to avoid conflicting results and ensure accuracy.

Our Happy Mothers

Excellent product! I am using it along with the Billings ovulation method and it is just a perfect combination for me since the Billings method tells me my fertile days and this one not only knows when I am fertile but also when I am ovulating!

Maria Palito

Happy mother from LA

 The KNOWHEN® saliva test has been a fantastic addition in our quest for pregnancy. It is so empowering to have a visual component to see your own hormone changes and predict fertility. It is so much cleaner to use and less wasteful than the plastic monitors and plastic urine sticks.

Willie Ryan

Happy mother from California

 This product empowers women to have reliable information regarding their fertility. Knowledge is power and this gives reliable information to all who use it. I give it to my family and friends who want to know when they are fertile to conceive and those who want a non-invasive and drug-free form of birth control.
