Regular cycle

What are the characteristics of regular cycles?

Classification and Distinction from Other Cycle Types

A regular cycle is less common than one might initially think. While, for example, 70% of women tend to have irregular cycles Of those who do, only about 3% have a relatively regular cycle. A characteristic feature is that the cycle length varies only minimally—usually by no more than ±3 days.


Also shorter cycles are not usually considered irregular. In fact, a shorter cycle length is often accompanied by very little variation in the intervals between periods.


Other Cycle Types may occur regardless of whether they are regular or not.

Determining ovulation in women with regular cycles

Ovulation can vary even in regular cycles

Do you have very regular cycles that vary in length by no more than 3 days? If so, you’re one of only 3% of all women with such a consistent cycle.* Even if your periods are relatively regular, that doesn’t necessarily mean you’re ovulating!

In fact, it can vary from cycle to cycle. That’s why the consistency of the length of your second phase is very important for assessing the health of your cycle. Incidentally, only 14% of all women correctly identify their ovulation based on physical sensations.** OvulaRing users, on the other hand, know their cycle inside and out and know exactly when they’re ovulating.

Menstruation is not proof of ovulation

Unfortunately, a regular menstrual cycle is not proof that ovulation is occurring. Menstrual bleeding results from the shedding of the uterine lining. It is therefore also known as withdrawal bleeding. Recurring hormonal changes in the body are fundamental to the interplay between ovulation and menstrual bleeding.

It is entirely possible that hormonal changes are sufficient to alter the uterine lining but do not trigger ovulation.

Benefits of modern cycle tracking with OvulaRing

Suitable for all cycle types

Is your cycle super short, extremely long, or even very irregular? OvulaRing tracks your personal cycle, no matter what Cycle type you are. The OvulaRing method works for all types of cycles. This has also been confirmed in three medical studies covering a wide range of cycle types.

Continuous measurement

With traditional basal body temperature tracking, you don’t measure your temperature continuously, but only once a day. To analyze your personal cycle even more accurately, however, OvulaRing measures your temperature around the clock and records 288 data points every day. This provides much more information for pinpointing your fertile days. OvulaRing also recognizes your very own cycle pattern and provides you with accurate results.

OvulaRing is just as easy to use and feels even less noticeable than a tampon. When you wear OvulaRing, you can go about your daily life just as you always have. For example, you can exercise or go to the sauna. You can still have sex and enjoy your life. The automatic measurement inside your body always provides accurate results. It doesn’t matter what your daily routine looks like—the measurement works regardless.

OvulaRing can reliably tell you whether you’re ovulating. This helps you determine whether your cycles are healthy. The app starts by learning your unique cycle patterns in detail. Once your cycle patterns have been identified, it provides you with a daily update on your fertility status. How OvulaRing Works.
