Why choose saliva testing over urine strips?

Urine ovulation strips track the LH surge, which usually happens close to ovulation. But if you want to understand your fertile window earlier, saliva testing offers a different advantage.

KNOWHEN® is based on changes in estrogen levels, using your own saliva to help reveal your fertile pattern. No chemicals. No algorithm guesses. Just your body showing you what is happening.

With KNOWHEN®, you can track up to 5 fertile days for conception — in a reusable, private, lipstick-size device that is easy to keep with you at home or while traveling.

For best results, use it daily first thing in the morning, before eating, drinking, or brushing your teeth. Life changes, stress, excitement, travel, and routine changes can all affect your cycle, which is why daily tracking can make such a difference.

One device. Your saliva. Your natural cycle.

PCOS is one of the most common hormonal concerns many women face today — and for some, it can make understanding the cycle and fertile window more difficult.

Sometimes, women are doing everything “right,” but still feel confused by their body’s signals. Irregular patterns, unexpected cycle changes, weight changes, excess hair growth, or difficulty conceiving can all be signs that something deeper may be going on.

That’s why paying attention to your body matters.

The KNOWHEN® Ovulation Microscope is designed to help women track their fertile days by observing saliva ferning patterns connected to hormonal changes. It can support you in identifying your most fertile window — up to 5 days for conception — while also helping you become more aware of unusual or unexpected cycle patterns.

It is not a diagnostic device and it does not replace a doctor. But if you notice repeated abnormal patterns or symptoms that concern you, it may be a sign to speak with a healthcare professional.

Understanding your cycle is not only about fertility — it is also about knowing your body better.

Track your cycle. Notice your patterns. Listen to your body.

Once again, I want to repeat something I truly believe:

Infertility is not always an epidemic — sometimes, it is a lack of knowledge, timing, and understanding of the female body.

During clinical studies with KNOWHEN®, we compared our saliva ovulation test with blood tests and ultrasound sonograms. The correlation was extremely high, which was truly remarkable.

One of the most powerful stories was a woman who had been trying to conceive for three years. She was healthy — she was simply missing her fertile window. After using KNOWHEN®, she conceived in the first month.

This is why fertility awareness matters.

KNOWHEN® helps women better understand their cycles, identify ovulation naturally, and feel more confident on their fertility journey.

Knowledge. Timing. Awareness.

This is currently my favorite part of my morning routine. ✨

Which is kind of funny, because a few months ago, I honestly wouldn’t have cared about tracking my cycle this much.

I’ve been using KNOWHEN® to help me track my cycle in a simple, natural way using just a tiny drop of saliva.

No strips.
No needles.
No complicated routine.

Because understanding your body shouldn’t feel stressful — it should feel empowering.
