Why “the cycle” isn't the same for all women

Biology is unique to each individual—and so must be the diagnosis

There is no such thing as a “standard cycle.” Cycle length, the day of ovulation, and the length of the follicular and luteal phases vary from woman to woman—and often from cycle to cycle. That is precisely why personalized cycle tracking is needed—one that doesn’t just count calendar days, but records actual body data and evaluates it over time.

Learning from patterns instead of guessing

Generalized calculation methods and spot measurements often overlook subtle patterns, such as shifted ovulation, fluctuating luteal phases, or anovulatory cycles. OvulaRing continuously measures inside the body and identifies individual patterns that show you which cycle type you are—today and over time.

How do I determine my cycle type?

To determine your cycle type, you should be able to answer the following questions:

What is the average length of my cycle?
How long is the luteal phase of my cycle?
How much does the length of my cycle vary from cycle to cycle?
How much does my ovulation day vary from cycle to cycle?
How often do I have a cycle without ovulation?
What significant external influences am I currently exposed to?

With this information, you can determine your own cycle type.:

Understand zur cycle: How OvulaRing works

1. wear OvulaRing

OvulaRing is inserted into the vagina like a tampon when your period stops. Independent of external influences, it automatically records your temperature inside the body. A value is recorded every 5 minutes and your individual fertility patterns are recognized.

2. transfer data

The recorded data is simply transferred with the OvulaRing app. The evaluation of your cycles is also displayed here. You can also keep a cycle diary and receive important information. The security of your data has top priority.

3. evaluate menstrual cycle

The app analyzes your cycle with the help of medical algorithms. In addition to cycle length, ovulation day and length of the cycle phases, you are also offered medical evaluations. There is a daily conception probability and an ovulation forecast for the following month.
