5 Why is the picture unclear?

There are several explanations. You may have applied too much saliva, the saliva has not completely dried, the picture has not been focused, or the diopter has not been adjusted. Simply twist the lens and adjust the focus.

6 Can an oral or gynecologic infection affect the picture results of the device?

It might. Certain types of infections and diseases may affect the saliva crystalline structure.

7 When is the best time to use the KNOWHEN® Ovulation Test?

For accurate, reliable test results the ONLY recommended time to test your saliva is first thing in the morning before brushing your teeth, eating or drinking. Certain factors such as food, alcohol or smoking may negatively affect the analysis of saliva. Therefore, we recommend not eating or drinking anything before the test.

8 Can I use the KNOWHEN® Ovulation Test during menstruation?

It can be used at any point in the menstrual cycle. It is a good idea to use it every day, even during your menstrual cycle, so you do not break your daily habit of testing. It is not unheard of to accidentally ovulate during your menstrual cycle and get pregnant.

9 Can the KNOWHEN® Ovulation Test 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 we recommend that you test first thing in the morning when your saliva is uncontaminated.

10 Can I share the KNOWHEN® Ovulation Test with someone else?

Yes but for reasons of convenience and hygiene, we don't recommend it.

11 Can I use more than one KNOWHEN® Ovulation Test?

Women that travel often or live in two locations frequently purchase more than one KNOWHEN® Ovulation Test for personal convenience.

12 The light on the device is not turning on. What should I do?

The light system is designed for long-term use. Considering that the KNOWHEN® Ovulation Test should not be stored in the bathroom or in other humid areas, your batteries should last at least a year or more if kept in dry conditions. We do not have control over the warehousing conditions of retailers where you purchased the product, so we recommend that you make sure the batteries inside your device are kept clean and dry.

Health Questions

13 My menstrual cycle is irregular, can I still use KNOWHEN®?

Yes. Nobody is more familiar with your monthly cycle than you. Fertility cycles average 28 days, but can be much shorter or longer. The KNOWHEN® Ovulation Test can help you determine the window of time you are ovulating each month, and this is not dependent on your cycles being regular.

14 What will the monitor show if I am already pregnant?

In most cases, the reading will only show a dotted infertile picture.

15 Why do some women have regular menstrual cycles and still have a problem conceiving?

Menstrual cycles and ovulation cycles are separate. An estrogen surge or ovulation may not occur every time you menstruate.

16 Will I see ovulation at the same time each month?

You may although most women do not. For those women who do ovulate at/near the same time each month can attribute this to a second estrogen surge near the end of their cycle. Some women over the age of 27 ovulate only once every 10 months.

17 Have any clinical studies been done on the KNOWHEN® Ovulation Test?

Yes. Several clinical trials have been done on the KNOWHEN® Ovulation Test and all the results show a 98+% accuracy rate on the day of ovulation which appears as a fern pattern 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 occur and shows the appearance of a fern pattern within dried saliva on the KNOWHEN® microscope.

18 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 women had to help them monitor their ovulation pattern when trying to get pregnant.

On average, women 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® Ovulation Test 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.

19 Can fertility drugs affect the results seen on the KNOWHEN® Ovulation Test?

Yes, and this is why if you have monitored your ovulation cycle for a few months prior to taking traditional infertility medication, you will know your normal pattern. Knowing your normal pattern allows you to see the effect of traditional infertility medication on your cycle and it can help you detect when ovulation is about to occur.

20 Can I show my fern pattern results to someone?

Yes, just do not touch or disturb the saliva. Undisturbed saliva will keep its fern pattern results as long as it is not touched, disturbed or subjected to other environmental changes.
