Frequently Asked Questions
No, the OVUL fertility tracker cannot detect pregnancy. While some wonder “will ovulation test detect pregnancy” or “would an ovulation test detect early pregnancy”, OVUL is designed to track ovulation through ferning patterns in saliva and monitor estrogen changes. For pregnancy detection, you should use a dedicated pregnancy test.
You can purchase a saliva test kit for hormones online through our official store and selected partners. These tests are convenient for home use, whether you need an estrogen saliva test, an ovulation saliva test, or a full hormone tracker device. Always make sure you’re buying from a reliable source.
Ovul works by analyzing ferning patterns in saliva, which change throughout the menstrual cycle due to hormonal fluctuations. This saliva test for ovulation uses AI-powered pattern recognition to interpret estrogen trends. Unlike a blood or saliva test for hormones done in a lab, Ovul is a non-invasive, at-home solution that also serves as a fertile window tracker and ovulation tracker online.

Ovul offers several advantages over traditional urine and blood tests. It's non-invasive, easier to use, and doesn’t require trips to the clinic. While urine and blood tests measure hormone levels directly, Ovul uses a saliva test for ovulation and tracks estrogen through ferning patterns, which naturally reflect hormone changes. This makes it a more convenient hormone tracker device and fertile window tracker for daily, at-home monitoring compared to standard methods.

Ovul tracks estrogen changes in saliva, visible as ferning patterns under the microscope. Research is underway to expand saliva testing to include progesterone saliva tests and other hormones.
A saliva test kit for hormones is non-invasive, reusable, and accurate. It helps monitor estrogen changes through saliva test ovulation patterns and can sometimes include progesterone saliva tests. Compared to urine strips, it’s easier, cleaner, and more eco-friendly.
