Daysy Birth Control Review 2022: A Natural Birth Control

Birth control can be confusing and overwhelming. Some people have risk factors that make traditional birth control methods, such as the pill and the IUD, less optimal.

Those looking for a natural, hormone-free birth control method may be interested in Daysy, a fertility tracker designed for people who want to get pregnant. Some people are interested in Daysy as an alternative to hormonal birth control or a supplement to family planning tools.

Here’s what you need to know if you’re considering using Daysy.

Daysy is a small medical device that functions as a fertility tracker. It uses your daily temperature to detect when you are most fertile or likely to be pregnant during your cycle.

The small device takes your temperature every day and connects with a free application, where you can see information related to your fertility.

Anyone with a female reproductive system can use Daysy. Although designed to help users conceive, some people like to use Daysy’s fertility tracking features as part of their natural birth control method. Daysy, in general, can be a great resource for those who want to learn more about their fertility.

Knowing when you are fertile can increase your chances of getting pregnant if that is your goal.

Daysy may be an option for those looking for hormone-free birth control.

Daysy works by increasing your fertility awareness. It is the awareness of the days that you are fertile so that you can make family planning decisions accordingly. During your fertile window you are more likely to get pregnant than on the days outside your fertile window.

It uses your basal body temperature and menstrual data to calculate when you are more likely to get pregnant and when you are less likely to get pregnant. Daysy takes your temperature with an accurate sensor, saves your data and calculates your fertility status.

Daysy indicates the fertility status by using the lights on the device:

  • Red means you are more likely to get pregnant.
  • Green means you are less likely to get pregnant.
  • Red flashing lights indicate the predicted day of ovulation.
  • Yellow lights can be an indication of cycle fluctuations or potentially fertile days.

Powered by a self-learning algorithm, Daysy is designed to reduce the potential for user errors or to take into account factors such as stress and travel. It is based on a database with more than 5 million menstrual cycles and 500,000 users to extract data, according to the company.

Daysy is easy to use, but it should be used every day. And even then, this is not a fool-proof method. In this way, it is similar to the pill, which should be taken daily and at about the same time each day. It’s okay if you forget to take a measurement every now and then, but your results will be most accurate with consistent daily use.

You will use Daysy first thing in the morning before getting out of bed. It is recommended to get at least 3 to 4 hours of sleep before using Daysy.

To use Daysy:

  1. Press the activation button once to see your predicted fertility status. Press it again to start measuring your temperature.
  2. Remove the protective shell over the sensor and place the sensor under your tongue. Do this while lying down, and do not engage in any activities before this step.
  3. The device will beep when the measurement is recorded.

Part of using Daysy involves recording menstruation. When you are on your period, press the activation button until a violet light appears and the device beeps once.

At the beginning, Daysy will be in the learning phase. Expect to see lots of yellow lights as Daysy’s algorithm learns more about your fertility. The more you use Daysy, the more it learns from you.
