How to use your fertility chart

Ovia Fertility makes it easy to track your fertility and get accurate ovulation and fertile window predictions. Your fertility chart is an important part of that because it contains all of your fertility data in one place, allowing you to see how all your data works together. What’s your temperature around your fertile window? Are you having sex on your ovulation date? Is your cervical fluid always the same right before your fertile window? Your fertility chart can keep track of all your most important information and help you identify patterns and trends unique to you.

What is on the fertility chart?

You can find your fertility chart by navigating to the left menu in Ovia Fertility and tapping “Fertility chart.” There, you’ll see all your fertility data mapped in one comprehensive graph. Your fertility chart contains all your essential fertility data: your fertility score, basal body temperature, intercourse, and cervical fluid. It will show this data with the dates for your period and fertile window, so you can see how it relates to your entire cycle and fertility health. And if you’re TTC, this info makes it easy to understand when you’re most fertile – and when you may want to pencil in some baby-making.

Fertility score

Your fertility score is a number from 1-10, with a 10 indicating that you are at peak fertility and have the highest chance of conceiving for this cycle. Viewing your fertility score as a layer on your fertility chart is a clear and simple way to understand how your fertility changes throughout the cycle and how closely your basal body temperature and cervical fluid consistency might be able to signal when you are approaching ovulation and the fertile window. This number helps makes it easy to understand when you’re most likely to get pregnant.

Basal body temperature

Your basal body temperature (BBT) can change throughout the menstrual cycle. Many people notice a slight dip in BBT right before ovulation, and then a spike in BBT immediately following ovulation. These are due to fluctuations in your hormone levels, specifically progesterone. Your fertility chart is the best place to view all of your basal body entries and visualize these changes.


This one’s not too complicated. When you log intercourse, it will show up on your fertility chart as a heart-shaped data point! This will allow you to keep track of whether you took full advantage of your fertile window, plus any other romantic evenings. If you log consistently, this could help you know your exact date of conception later on.

Cervical fluid

Like BBT, your cervical fluid (also called cervical mucus) can change greatly throughout the cycle. Cervical fluid helps sperm travel through the cervix and into the fallopian tube and becomes more “fertile” as you get closer to ovulation. Ovia Fertility has identified four levels of cervical fluid: “nothing felt, nothing seen,” “school glue,” “watery,” and “egg whites.” Cervical fluid tends to be at its driest and least fertile (“nothing felt, nothing seen”) during and shortly after menstruation. It tends to become more liquidy, clear, thin, and stretchy (“egg whites”) as you progress through your cycle towards ovulation.

Viewing your cervical fluid data on your fertility chart can help you understand how it changes throughout your personal cycle, and will let you know if there seem to be inconsistencies between your cervical fluid quality and your fertility score.

Check your fertility chart often to learn more about your own unique cycle and see how your fertility changes throughout that cycle.
