How the OvulaRing ovulation calculator works

What is the OvulaRing ovulation calculator used for?

With the help of our ovulation calculator you can calculate your next ovulation and thus determine your fertile days. With this information you can better understand your cycle, get pregnant in a targeted way or support natural contraception. Please note, however, that using the ovulation calculator alone is not suitable as a contraceptive.

How to use the OvulaRing ovulation calculator

To get a result, you need to enter the date of your last cycle start (first day of your period) and at least the length of one of your last cycles. The result will be more accurate if you enter the lengths of your last 3 cycles into the ovulation calculator.

How exactly does the ovulation calculator work?

The OvulaRing ovulation calculator uses the findings of the OvulaRing method to calculate your next ovulation. Based on the entered cycle(s), the expected cycle length is determined. As the second cycle phase is more stable in time than the first, it is used for a more accurate estimate. The second cycle phase is usually between 11 to 15 days long. On average, it is 13 days.

How reliable is the OvulaRing ovulation calculator?

The reliability of the OvulaRing ovulation calculator is lower than that of the OvulaRing method, which precisely determines ovulation based on the continuous temperature curve. For our online ovulation calculator, the second cycle phase is assumed to be 13 days long, as this is the statistical mean value for this. For a more accurate result, the cycle must be recorded in full and ovulation determined exactly. Only a medically certified method like OvulaRing can offer you this.

Why the ovulation calculator is not suitable for contraception

  • Your cycle is individual: every woman has her own cycle. An ovulation calculator is based on average values. If your cycle is irregular, the calculator may make inaccurate or false predictions.
  • Data entry errors: An error in entering data, such as the first day of your period or the length of your cycle, can lead to inaccurate results.
  • Multiple fertile days: An ovulation calculator only determines the most likely day of ovulation. Based on this, the fertile days around ovulation are determined. However, sperm can survive in the body for several days, so it is not ovulation alone but your fertile days that are important.
  • Unexpected ovulation: Your ovulation can occur unexpectedly (earlier) under certain circumstances, which can lead to a false sense of security.
  • No guarantee: The ovulation calculator can only give you an indication of when your fertile days probably will be. Even if you have a very regular cycle and enter the data correctly, an ovulation calculator does not offer a 100% guarantee against an unwanted pregnancy.

If you want to use contraception, you should use reliable methods such as condoms, IUDs or hormonal contraceptives.

Determine your ovulation even more accurately now - with the OvulaRing method

Understanding your cycle: The importance of ovulation

What exactly happens in the body at ovulation?

On the day of ovulation, a mature egg is released from the ovary. This time can vary from cycle to cycle and is triggered by the increase in luteinising hormone (LH). The released egg travels to the fallopian tube where it is fertilised. At the same time, the lining of the uterus is built up for a possible pregnancy.

However, if the mature egg is not fertilised, the built-up uterine lining is later rejected and released as menstruation.

What are the physical signs of ovulation?

Ovulation is a natural process where some physical signs and symptoms may occur. Not all women experience these signs, and they can vary from cycle to cycle. The most common physical signs of ovulation include:

  1. Mid-cycle pain: a mild to moderate pain or pulling in the lower abdomen that occurs around the middle of the cycle and is therefore called mid-cycle pain.
  2. Cervical mucus: The consistency of cervical mucus changes during your cycle. During ovulation it often becomes clearer, more stretchy (spinnable) and resembles raw egg white.
  3. Breast sensitivity: Some women experience more sensitive or slightly sore breasts during ovulation.
  4. Changes in the cervix: The cervix may change in shape and position. It may be softer and positioned higher in the vagina during ovulation.
  5. Light bleeding: Some women may experience light, greasy bleeding called ovulation bleeding.
  6. Libido: Some women experience increased sexual desire during ovulation.

It is important to note that not all women experience these signs, and some may not even notice them. However, these signs can be quite helpful if you want to better understand your cycle. Using an ovulation calculator can also help to determine the timing of ovulation more accurately.

Calculate ovulation for irregular and fluctuating cycles

Calculating ovulation for irregular or fluctuating cycles requires patience and close cycle observation. If you have irregular cycles, we recommend that you fill in all the information in the ovulation calculator so that more cycles are recorded. Taking your body temperature with OvulaRing and observing your cervical mucus can provide additional clues. Ovulation tests can also be useful.

If you have very irregular cycles or persistent problems, it is a good idea to consult your doctor to find out what might be causing them. You can also get support from your doctor if you are having irregular cycles and your wish to have a baby is not fulfilled.

The best alternatives to the online ovulation calculator

These are the best alternatives to the online ovulation calculator:

1. OvulaRing method

OvulaRing is a medical cycle tracker that completely records your cycle and thus can accurately determine your ovulation. In addition, OvulaRing determines your fertile days and provides an up-to-date fertility status. Thanks to the patented method with vaginal temperature sensor, OvulaRing is suitable for all cycle types. As a certified medical device with app, OvulaRing is easy to use and as comfortable as a tampon. How OvulaRing works.

2. basal temperature method

In the ‘classic temperature method’, basal body temperature is measured once a day. This increases slightly during ovulation. The measurement of the basal body temperature requires a little discipline and practice in the evaluation.

3. cervical mucus observation

The consistency and appearance of cervical mucus changes during the cycle. During ovulation, the mucus often becomes clearer and more stretchy. Watching these changes can help you determine when you are ovulating.

4. ovulation tests

An ovulation test (urine test) detects the increase in luteinizing hormone (LH), which triggers ovulation. They are available in pharmacies, but cannot detect ovulation 100%. If you want to use them, you should inform yourself exactly about the safety of ovulation tests.

5. cycle apps

There are many mobile apps to track your cycle and calculate ovulation. Note that the accuracy of cycle apps just like online ovulation calculators is worse than that of medical methods like OvulaRing. These are often based only on the data entered and provide estimates and reminders.

6. regular medical examinations

If you have difficulties getting pregnant or want to understand your cycle in more detail, you can consult your gynecologist. She can perform examinations (ultrasound) and make recommendations.

7. ovulation calendars and tables

These tables and calendars can help you calculate the probable time of ovulation. The accuracy here is similar to online ovulation calculators and cycle apps.

Choosing the best method to determine your ovulation depends on your personal preferences and needs. To determine the time of ovulation as precisely as possible, medical methods such as OvulaRing are particularly suitable. To know the ovulation only approximately, an alternative method is also suitable.
