Natural birth control - safe and hormone-free


Many women wish natural birth control method, since in contrast to hormonal birth control the natural processes of the body are not affected. The basis for safe, hormone-free birth control is the precise observation of specific physical indications that change over the course of the cycle. OvulaRing can help you to understand the changes in your body and thereby accurately identify the fertile days, without the need to measure your basal body temperature each morning.

You want to use natural birth control? OvulaRing supports you optimally with hormone-free birth control and natural family planning (nfp). The reliable determination of your fertile days helps you to precisely understand changes in your body. This makes it easy for you to use natural birth control. OvulaRing detects your fertile and infertile days safely and objectively, without the hassle of taking your temperature in the morning. OvulaRing also interprets the cycle curves for you and shows you fertile and infertile days.

The evaluation is carried out exclusively by the myovularing software; the biosensor and the OvulaRing app do not provide any independent results. The use of the myovularing software does not constitute birth control, as it does not interfere with bodily functions and cannot prevent the transfer of sperm or the fertilisation of eggs. The calculated results only provide information on the probability of conception and are not a substitute for individual measures or means of pregnancy prevention (e.g. condom).

Supporting the symtothermal method with OvulaRing

Symptothermale Methode - natürlich verhüten

With the symptothermal method, changes in the cervical mucus and body temperature in the cycle are monitored carefully. The combination of observation, documentation and evaluation of both symptoms enable the fertile days to be precisely identified with a little practice. If you wish to practice natural birth control, you must refrain from sexual intercourse during this phase or use mechanical birth control methods such as condoms or a diaphragm. OvulaRing takes on the temperature monitoring and evaluation role, helping you to practice the symptothermal method.

The simple way to support natural birth control

How does the temperature change in the course of the cycle?

Body temperature rises after ovulation with the simultaneous release of the hormone progesterone, increasing by 0.25 – 0.5 °C. If the temperature remains elevated for 3 days, you can be sure that ovulation has occurred and that the fertile phase is complete. OvulaRing detects the smallest changes in temperature even before ovulation and shows you your fertility days, without the need for morning temperature monitoring.

How does the cervical mucus change during the menstrual cycle?

The consistency and quantity of cervical mucus change during the cycle. Under the influence of oestrogen the cervical mucus becomes so thin that it could be drawn out like a thread and spun. Shortly before ovulation this spinnability is at its greatest and the secretion has maximum permeability for sperm. In contrast, in the infertile days the cervical mucus is viscous and thick, making it barely permeable for sperm and germs. In the OvulaRing menstrual cycle diary you can document the changes in the cervical mucus precisely, enabling you to monitor it.

How can OvulaRing help me?

OvulaRing is not a basal thermometer and is much more than a standard cycle tracker. OvulaRing records your body temperature continuously, 288 times a day. The high resolution measurement enables your individual cycle pattern to be recorded. Medical algorithms evaluate this and reliably indicate your daily conception probability in the software. In addition, with OvulaRing you can find out if your cycle is healthy or if there are signs of a hormonal cycle disorder. You can also use the software to share your data with your doctor.

* The output of the daily updated conception probability is usually done from the second cycle, because OvulaRing first gets to know your individual fertility patterns in the first cycle.

** The ovulation prediction is usually done for the fourth cycle, because at least three cycles with ovulation are needed for reliable calculation. If ovulation fluctuates by more than 8 days in successive cycles, a reliable prognosis cannot be issued. However, this does not affect the calculation of the daily probability of conception, which is why OvulaRing can make precise statements even with irregular cycles.
