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 that acts as an alternative or supplement to birth control and 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 calculate when you’re fertile, helping you reduce or increase your chances of conception.

The tiny 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 pills, get shots, or undergo any medical procedure, so it has no side effects. It is a non-invasive natural birth control option, but requires daily use.

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

Most birth control methods are hormonal and can influence hormone levels and have other side effects. Daysy may be an option for those looking for hormone-free birth control.

Daysy can also be a good resource for those looking to learn more about their fertility. Knowing when you’re fertile can help increase your chances of conceiving if that’s your goal.

Daysy works by increasing your fertility awareness. It’s awareness of when you’re fertile, so you can make family planning decisions accordingly. On days when you are fertile, you are more likely to conceive than on days when you are not fertile.

It uses your basal body temperature and menstruation data to calculate when you’re more likely to conceive and when you’re less likely to conceive. Daysy takes your temperature using an accurate sensor, stores your data and calculates your fertility status.

Daysy signals fertility status using the lights on the device: red means you’re more likely to conceive and green means you’re less likely to conceive. Red flashing lights indicate the expected day of ovulation. Yellow lights can be an indicator of cycle fluctuations or potentially fertile days.

Powered by a self-learning algorithm, Daysy is designed to reduce the risk of user errors or 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 from.

Daysy is simple to use, but should be used every day. And even then, it’s not a foolproof method. In this way, it is similar to the pill, which must be taken daily and at around the same time each day. It’s okay if you forget to take a measurement once in a while, but your results will be more accurate with consistent daily use.

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

To use Daysy:

  1. Press the activation button once to display your predicted fertility status. Press it again to start taking your temperature.
  2. Remove the protective cap on the sensor and place the sensor under your tongue. Do this while lying down and do not engage in any activity before this stage.
  3. The device beeps when the measurement has been saved.

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

At first, 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 about you.

Daysy is available for purchase on the company’s website,

It is also available on:

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

“It’s a great alternative if you [are] trying to avoid hormonal birth control,” writes Amazon user Stori Evans. “I’m still getting to know this device, but after a while you get used to it. It also allowed me to know more about my body.

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

“It never syncs properly with the app. You have to keep doing it over and over again [until] it finally works. When I enter information, half the time it is not saved. It takes about 2 minutes to take your temperature,” says a reviewer on TrustPilot.

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

There are no side effects associated with the use of Daysy. It’s as safe as taking your temperature with a regular thermometer. It is also registered with the FDA.

Fertility and family planning are complex, so there are a wide variety of birth control methods. Birth control can be used to prevent unwanted pregnancies, but certain family planning tools can also help those who wish to conceive.

The best option for you depends on your goals, and Daysy might not be right for you. However, there are other natural birth control methods to consider.

A popular alternative to Daysy is to simply track your cycle and take your temperature yourself. Tracking and understanding the rise and fall of your basal body temperature throughout your cycle can help you predict which days you are fertile.

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

If the fertility awareness associated with Daysy is what intrigues you, consider the rhythm method. It involves tracking your menstrual cycle and using the data to predict future cycles and get to know your body better.

If you are sexually active and not interested in conceiving a pregnancy, contraception should be a concern for you. There are many options to use.

Hormonal contraception is generally considered safe and well tolerated with few or no side effects for the majority of users.

However, some people may have risk factors, health conditions, or sensitivities that make them more prone to side effects from hormonal birth control methods.

The side effects of contraceptives vary depending on the type and your body.

Common side effects of birth control include:

  • missed periods
  • tracking
  • acne
  • breast tenderness
  • nausea
  • headache

They can also have health consequences, such as increased blood pressure.

Natural birth control options, like Daysy, are free from side effects and health risks, making them safer.

Getting started with Daysy is simple.

You can start by ordering your Daysy tracker and downloading the app. Before first use, you will need to charge the device. After that, you will need to recharge it using the USB cable every 1-2 months.

Daysy comes with everything you need, so you don’t need to buy anything else. Unlike other birth control methods, you don’t need to buy supplies on a monthly basis.

Consult your doctor if you are taking medications that affect your body temperature. This may interfere with Daysy’s effectiveness.

If you are currently using other forms of birth control given to you by your doctor, check if Daysy is compatible with your existing method. Daysy should not be used while taking hormonal contraceptives.

How effective is Daysy?

Daysy claims to be 99.4% accurate. This was confirmed by a study funded by the company. Unaffiliated researchers have found that Daysy isn’t as accurate as the company claims, and the company the article has been removed A little after.

Does insurance cover Daysy?

Daysy does not accept health insurance as a method of payment, but you may be able to get a portion of the cost reimbursed by your health insurance plan.

He is also eligible for Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA).

Is Daysy worth it?

Daysy is expensive, but it’s a one-time expense. Over time, it can be cheaper than ovulation test strips, birth control pills, IUDs, and other forms of birth control and family planning resources.

If you are looking for a natural contraceptive, it may be worth it, but that is subjective.

Can you get pregnant when you’re not ovulating or having your period?

You can still get pregnant during your period and outside of ovulation, but it’s rare. You can also get pregnant with birth control.

For those looking for a natural birth control method, Daysy is a suitable option. It is easy to use, without side effects and reliable. Although it requires a large initial investment, it can be more profitable over time.

If Daysy isn’t right for you, there are many other birth control methods available, from conventional condoms to other natural or non-hormonal birth control methods.

Everyone is different, so it may take some trial and error to find the right birth control method for you.
