FAQ
Ovulation tracking — common questions
How Vyla helps you understand your fertile window and ovulatory patterns.
Still have questions? Contact us- What is ovulation tracking?
- Ovulation tracking involves monitoring biological signals — such as basal body temperature, LH hormone levels, and cervical mucus — to identify when ovulation is likely to occur in your cycle, and understand your fertile window.
- How does Vyla track ovulation?
- Vyla combines your logged cycle history, BBT temperature readings, LH test results, and cervical mucus observations to estimate your fertile window and likely ovulation timing each cycle.
- What is a fertile window?
- The fertile window is the days in your cycle when conception is biologically possible — typically the 5 days before ovulation and the day of ovulation itself, as sperm can survive for several days. Vyla estimates this window based on your individual cycle patterns.
- How do I log LH tests in Vyla?
- In the Vyla daily log, you can record your LH test result as negative, low, high, or peak surge. Over several days around your expected fertile window, this helps identify the LH surge that typically precedes ovulation.
- Does Vyla provide fertility advice?
- No. Vyla is a wellness app that helps you understand your body's patterns. It does not provide fertility treatment guidance, diagnose conditions, or replace advice from a reproductive healthcare professional.
- Is ovulation tracking free in Vyla?
- Basic fertile window estimates and LH test logging are available on the free plan. BBT trend analysis and deeper ovulation insights are available on Vyla Premium.
