FAQ's
How Does a Home Ovulation Test Work?
Home ovulation kits are a breakthrough in fertility tracking, designed to help women trying to conceive or prevent unexpected pregnancies. These kits detect the surge of luteinizing hormone (LH) that occurs before ovulation, providing essential insights into your cycle.
A saliva-based ovulation test is non-invasive and works by identifying unique patterns in dried saliva that signal ovulation. It’s reusable, cost-effective, and eco-friendly, allowing you to track your cycles over time without the waste of disposable tests.
Using a home ovulation kit is simple and empowers women to manage their reproductive health discreetly and comfortably from home. Whether you’re new to fertility tracking or experienced, these kits offer both ease and accuracy, making them a reliable tool for family planning.
No matter where you are on your fertility journey, a home ovulation kit can provide valuable insights, helping you take control of your reproductive health with confidence.
How does the KNOWHEN® Saliva Ovulation Test work?
The KNOWHEN® Saliva Ovulation Test works by detecting changes in estrogen levels through your saliva. As you approach ovulation, estrogen levels rise, which is visible in the pattern of salt crystals in your saliva. You use a reusable microscope to view your saliva on a test slide, interpreting the pattern to identify your most fertile days.
Is the KNOWHEN® test accurate?
Yes, the KNOWHEN® test is clinically tested with an accuracy of 98.9%. It is a reliable tool for tracking ovulation and fertility windows, backed by scientific research and user testimonials. However, individual results may vary based on how consistently the test is used.
Is the KNOWHEN® test reusable?
Yes, the KNOWHEN® test is designed to be reusable. Unlike traditional test strips, which are single-use, the KNOWHEN® device can be used repeatedly, offering a cost-effective and eco-friendly solution for ovulation tracking.
How often should I test my saliva?
To track your ovulation cycle accurately, it’s recommended to test your saliva daily, especially during the second half of your cycle. This will help you monitor changes as you approach ovulation.
Is the KNOWHEN® Saliva Ovulation Test easy to use?
VERY EASY! Simply collect a small sample of saliva, place it on the test slide, and view it under the provided microscope to interpret the results. The process takes just a few minutes each day.
Can I use the KNOWHEN® test if I have irregular cycles?
Yes, the KNOWHEN® test is suitable for women with irregular cycles. Since it tracks estrogen levels rather than relying solely on menstrual timing, it can help women identify their fertile window regardless of cycle regularity.
What does the lifetime warranty cover?
The lifetime warranty covers manufacturing defects. The warranty process is explained in the product instructions. Note: Batteries are not included in the warranty, but new batteries are provided in the kit. A copy of the purchase receipt is required for any exchanges.
Have any clinical studies been done on the KNOWHEN® Saliva Ovulation Tester?
Several clinical trials have been done on the KNOWHEN® medical device and all results show a 98% accuracy on the day of ovulation to show a fern pattern appear on the microscope.
The studies correlated the detection of a surge in the Luteinizing Hormone (LH) present in the body at the time when ovulation is about to occurs and shows the appearance of a fern pattern within dried saliva on the KNOWHEN® microscope.
Can the KNOWHEN® Saliva Fertility Monitor give me misleading results?
Yes, if you test your saliva at any other time than first thing in the morning you can get a false result. Any food or drink you consume that contains salt can change your result and this is why it is recommended you test first thing in the morning before you brush your teeth when your saliva is uncontaminated.
Why not use the traditional Basal Body Temperature Method to detect ovulation?
Using the Basal Body Temperature (meaning taking your temperature first thing in the morning before you get out of bed) has been used for years to detect ovulation BUT it will only show you that ovulation has occurred. For many years this was the only available method woman had to use to help them monitor their ovulation pattern when trying to get pregnant.
On average women trying to get pregnant have eleven to twelve chances per year to get pregnant and having intercourse before, during and after ovulation will dramatically increase your chances of getting pregnant.
The KNOWHEN® medical device not only shows a woman when she has ovulated but shows her the crucial few days prior to ovulation when she is most fertile and has a higher probability of conceiving.
What if I am uncomfortable logging my fertility cycle in an app?
No problem! The KNOWHEN® Saliva Ovulation Test comes with a manual log booklet so you can keep off-line track of your cycle.
It's important to note that the data you input into the KNOWHEN® Mobile App is not on a cloud-based storage system. It is stored on your phone for your own personal use and it is not shared with any third party.
How long will the KNOWHEN® Tester last?
With careful use the KNOWHEN® medical device can last years, as long as you do not let it get wet, drop it or interfere with the light housing unit.
What is your return policy?
The KNOWHEN® Saliva Ovulation Test is a medical device, therefore we cannot accept returns. We do offer a lifetime warranty that allows for a replacement should the device stop working. Please contact us ASAP if for any reason your device stops working (though it shouldn't), and our team will get to work issuing you a new device.
