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 IUD, less than optimal.

Those looking for a natural, hormone-free method of birth control may be interested in Daysy, a fertility tracker that acts as an alternative or complement to birth control and family planning tools.

Here’s what you need to know if you want to use Daysy.

Daysy is a small medical device that acts as a fertility tracker. It uses your daily temperature to calculate when you’re fertile and helps you decrease or increase your chances of conceiving.

The little device takes your temperature every day and pairs with a free app where you can view information about your fertility.

Daysy doesn’t require you to take any pills, get an injection, or undergo any medical procedure, so it has no side effects. It is a natural birth control option that is non-invasive but requires daily use.

Anyone with a female reproductive system can use Daysy. It is good for those who are looking for a natural alternative to existing birth control methods such as the pill, injection and IUD.

Most birth control methods are hormonal and can affect hormone levels and cause other side effects. Daysy may be an option for those looking for non-hormonal birth control.

Daysy can also be a good resource for those who want to learn more about their fertility. Knowing when you are fertile can increase your chances of conceiving if that is your goal.

Daysy works by increasing your fertility awareness. This is awareness of the days when you are fertile so you can make family planning decisions accordingly. You are more likely to get pregnant on the days you are fertile than on the days you are not.

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

Daysy uses the lights on the device to signal fertility status: red means you’re more likely to get pregnant, and green means you’re less likely to get pregnant. Flashing red lights indicate predicted ovulation day. Yellow lights can be an indicator of cycle fluctuations or potentially fertile days.

Powered by a self-learning algorithm, Daysy was designed to reduce the potential for user error or to take into account factors such as stress and travel. It is based on a database of over 5 million menstrual cycles and 500,000 users to pull data from.

Daysy is easy to use but needs to be used every day. And even then, it’s not a foolproof method. In this way, it is similar to the pill, which needs to be taken every day and at about the same time. It’s okay if you miss a measurement every once in a while, but your results will be most accurate with consistent daily use.

You use Daysy first thing in the morning before you get up. It is recommended to sleep at least 3 to 4 hours before using Daysy.

To use Daysy:

  1. Press the activation button once to see your predicted fertility status. Press again to start temperature measurement.
  2. Remove the protective cap over the sensor and place the sensor under your tongue. Do this while lying down and do not perform any activity prior to this step.
  3. The device will beep when the measurement is recorded.

Part of using Daysy involves tracking menstruation. When you have your period, press the activation button until a purple light appears and the device beeps once.

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

Daysy can be purchased from the company’s website. usa.Daysy.me.

It is also available on:

Daysy is highly rated TrustPilot and Amazon. Customer reviews praise the company for good customer service and warranty. Many customers write about their positive experiences with Daysy to prevent or plan pregnancy.

“This is a great alternative if you [are] try to avoid hormonal birth control,” writes Amazon user Stori Evans. “I’m still learning about this device, but after a while you get the hang of it. It also helped me learn more about my body.”

Other reviews are not so positive, stating that the company has faulty products, glitches in the app, and high prices. Many users experienced technical difficulties with the device and the app.

“It never syncs properly with the app. You have to do it over and over again [until] it finally works. When I enter information, half the time it doesn’t save. It takes about 2 minutes to take your temperature,” explains a reviewer on TrustPilot.

A common complaint among users is the high frequency of yellow days, indicating potentially fertile days or that Daysy is still learning. Some reviewers mention that despite using the device to prevent unwanted pregnancy, they still got pregnant.

The best option for you depends on your goals, and there’s a chance that Daysy isn’t right for you. However, there are other natural birth control methods that should be considered.

A popular alternative to Daysy is to simply track your cycle and take your temperature yourself. Tracking and understanding how your basal body temperature rises and falls throughout your cycle can help you predict your fertile days.

Daysy does that for you, but doing it yourself is an option if you’re having trouble with the app or want a budget-friendly option.
