Simple to use. Easy to understand. Made to support your cycle awareness.

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.
