Contraception without hormones

MY OVU is an innovative ovulation thermometer with an application designed to more accurately determine your fertile days.

By monitoring your basal body temperature (BBT), you can determine your fertile and infertile days. Infertile days occur once or twice during the cycle: at the very beginning of the cycle (up to 5 days before ovulation) and 24–48 hours after ovulation. They last until the next menstrual period.

IMPORTANT! If you have a short cycle, you should only assume one period of infertility – the phase after ovulation. The egg can only be fertilized within 48 hours of ovulation! Days after ovulation are called absolute infertility and last until the next menstrual period.

Precision control that gives you freedom

No matter where or when you wake up, the device is with you. Convenient and easy to use.

The intuitive app will automatically track your fertile days. Forget about the paper notebook; we’ll handle everything for you.

The device has been created based on the needs of modern women. From now on, you can forget about morning discipline.

Gynecologists have been co-creating the concept of MY OVU from the beginning, supporting us with their knowledge and experience.

Precision control that gives you freedom

Trust the latest technology that guarantees the highest measurement precision.

Precision, convenience, discretion – the MY OVU ovulation thermometer is innovative in every way! It has made cycle tracking easier than ever before. We’ve placed a precisely designed computer system in a small, silicone vaginal ring. Safe, neutral, and comfortable for your body. Internal measurement of BBT using algorithms is much more accurate than traditional methods, which can underestimate fertile days by up to 24-48 hours.

How does it work?

Before going to bed, insert the disc into the vagina, like a tampon or menstrual cup. MY OVU will take the measurement and store the result in the device’s memory. In the morning, upon waking up, remove the disc and wash it. Transfer the data to the app, then put MY OVU back into the box.

Apply

Before falling asleep, place MY OVU in the vagina. The easiest way to do this is by bending the disc inward at the thickened area.

Fall asleep

MY OVU collects data while you sleep.

Synchronize

In the morning, remove the disk and wash it with soap. Turn on Bluetooth and send the data to your phone – just press the button on the disk’s bulge.

Read the measurement

In the app, you’ll find the current reading and forecasts for your cycle.

All the necessary information at your fingertips

The purple bar on the chart indicates the day of ovulation. The labels for days 1, 2, 3 indicate days of higher temperature, confirming ovulation.

In the calendar, you will find predictions for your future periods and ovulation, based on personalized data.

In the app, you can record your observations regarding, for example, the quality of cervical mucus and cervical position – they are also important for fertility analysis.

Proven effectiveness

Check out user reviews of MY OVU:

  • I think the app is really great. Until now, I’ve only had apps based on statistical data (like one day of period, etc.). Now I have data based on my individual measurements, based on my temperature. The app shows me the exact day of ovulation. For example, the FLO app gave me the day of ovulation 2 days earlier than it actually occurred according to MY OVU!
  • If I had this thermometer 15 years ago, I wouldn’t have to go for ultrasound scans for a year to check if I was ovulating in a given cycle and if I could get pregnant. The idea is fantastic. It’s super simple and really accurate. The temperature is given to the second decimal place, which is great.
