Frequently Asked Questions

I'm not seeing any ferning. What's wrong?

First, review the directions to make sure you are using the OvuScope correctly. Also, make sure you are looking at the entire region where the saliva has dried; ferning may occur near the edges of the region. However, if you still do not see any ferning throughout your cycle, there are several possible reasons. First, not all women fern. There could be many reasons, such as having a hormone imbalance or you may not be ovulating. In this case, please contact your physician. Second, ferning may be disrupted by smoking, eating, drinking (water, alcohol, etc.), brushing your teeth, how saliva is put on the slide, or where/when you did the test.

Why can't I focus the OvuScope?

To better focus, look at the edge of the square cutout of the slide and use the focus knob to adjust focus. Once the square cutout is in focus, move the slide over and refocus until you see small black objects on a green background. If you are still having trouble focusing the OvuScope, try again with your glasses off or make sure you are placing your eye close to the microscope’s eyepiece.

Can the OvuScope test give me a false positive?

Yes, ferning can appear if a saliva sample is taken after eating, drinking, smoking, or taking certain medications.

Ferning appears at random times. What's wrong?

Make sure that the saliva sample was taken prior to brushing your teeth, eating, drinking, or smoking. Also, an illness such as a cold, or some medications may affect the results. All the above have an impact on ferning and can cause you to see ferning at random times.

Does this work for women who have PCOS?

Yes, but the only issue is determining when you are ovulating over a longer time period. Generally speaking, a woman’s cycle is between 25-35 days. A woman with PCOS could go three months or longer without a regular cycle, so it may take many months to observe ferning.

What is the magnification?

60x.

Why is the image blurry?

Please adjust the focus until clear.  You also may need to allow the saliva more time to dry fully before viewing.

How much saliva do I need for testing?

Just a small drop.  Do not overfill the small square cutout.

My fern patterns look different from my friends. Is this cause for concern?

No, fern patterns are dependent on several factors that are unique to each person. Some women may fern more/less than others. After a few weeks of monitoring you will be able to immediately recognize what is normal and expected for you.

I saw ferning on the slide when I first took the sample but several hours later it was gone. How long can a sample stay on the slide?

For reliable results, look at samples that have just finished drying. Yes, it is possible for a dry saliva sample to be observable on the slide several hours later but this is not recommended as the sample can be affected by environmental factors such as temperature and humidity.

My ferning pattern results don't align with my BBT thermometer results. What does this mean?

BBT thermometers provide a shorter spike typically lasting 24-36 hours. However, ferning may last closer to 72-96 hours, providing an extended window in which to remain sexually active and maximize the chance of conception. Also, there are more factors that may affect your bodies temperature than those that may affect your saliva chemistry, such that the two methods may not coincide exactly.

Can the OvuScope be used as a contraceptive?

No, this device is not intended to be used as a contraceptive or pregnancy test, nor will it provide any indicative information during pregnancy. Use only as a means to monitor ovulation during your anticipated ovulation window.

How do I clean the slides?

Sides can be rinsed with warm water and dried gently with a soft cloth. Ensure there are no water marks or dust left behind as this can alter readings. Do not use any abrasive chemicals or cloths on the slide, such as alcohol, paper towels, etc. which may degrade or scratch the optical surface.

Can you use cervical fluid instead of saliva?

No, please only test using saliva.

Is this FDA approved?

A saliva-based ovulation method is considered a Class I device by the FDA and is not subject to FDA device approval, however, the company and this device are registered with the FDA.
