Mira FAQ

How Does Mira Work?

I'm trying to get pregnant. How can Mira help me?

Many couples try to conceive at the wrong time, simply because they don’t know when their most fertile days are. Researchers found that only 12.7% of women estimated their ovulation time correctly and only 55% of women estimated their ovulation within their fertile window. Mira tracks key fertility hormones concentrations to give you personalized insights into your cycle and maximizes your chances of getting pregnant.

How Mira is different from OPK?

The Mira Analyzer dynamically tracks hormone levels and gives you actual LH levels throughout your cycle. The technology in our app learns your cycles and detects the LH surge based on the quantitative hormone levels. Other OPKs detect ovulation off a static baseline LH, which can cause many false positives. No more hard-to-read “one line” vs. “two lines”! Your cycle information is automatically synced and analyzed by Mira so you don’t need to do any manual charting!

How Mira is different from BBT thermometers?

Your basal body temperature (BBT) increases after you ovulate. In contrast, Mira’s lab-grade technology gives your actual hormone concentrations and detects the entire fertile window up to 5 days before ovulation! BBT changes due to environmental and lifestyle factors. Mira learns your cycle, providing personalized ovulation detection for variable cycles.

How do I test?

Make sure your tests are performed according to the instructions below:

– Please leave the test wand in the urine sample for about 10 seconds. Sampling the urine either too long or too short can cause test errors.

– Please keep the sampling end of the test wands pointing down after sampling the urine.

– Please don’t shake the test wand after sampling the urine.

– Please insert the test wand immediately into the Analyzer after sampling the urine.

– Please insert the wand horizontally into the Analyzer while letting the Analyzer sit on a horizontal surface.

– Please insert the test wand all the way into the Analyzer.

Why is my hormone level low? / Why does the Analyzer not detect my surge?

Our hormone fluctuates from woman to woman and cycle to cycle. The pattern of the curve is more important than the absolute value. When ovulation happens, you should see a sudden increase of LH concentrations, although the peak value can vary greatly: from medium to high. Please test again in 6 hours once you see a medium or high test result to confirm if it is an LH surge.

Our LH goes up and down very sharply. The entire surge can be done within 24 hours. Therefore, it is very normal you see a surge in the morning, and back to none in the afternoon. Once you see the surge, you are ovulating in 12-24 hours, so it is the best chance to try for a baby. Please make sure you always use the first-morning urine or limit fluid intake for at least 2 hours before each test.

My LH level is high, what should I do?

The LH surge in an urine often peaks in the afternoons. However, each LH surge lasts 24-48 hours so you should see an elevated hormone level that morning. To confirm ovulation Mira’s algorithm will ask you to test again in 6 hours once it sees a high value. Once you see the surge, you are ovulating in 12-24 hours, so it is the best chance to try for a baby.

Can I use Mira to avoid pregnancy?

The data Mira provides can be useful for natural family planning and many of our users use it for this purpose such as preventing pregnancy! Mira will show you both fertile AND non-fertile days based on your unique hormone cycle. The Mira tracker automatically tells you which days to test based on your unique hormone profile and past cycle data, and it will learn over time to dynamically change these testing dates and frequency if needed. Nonetheless, it’s also important to note that no fertility tracker is approved by the FDA as a 100% sure-proof contraceptive.

Do you have Estrogen/hCG/Progesterone tests?

The Mira Fertility Tracker currently measures LH hormone. We are launching the Estrogen and Progesterone test wands by early 2020! Estrogen will precisely measure all fertile days. And Progesterone confirms if ovulation has happened which is very useful for people who try to avoid pregnancy in a natural way. Both test wands work perfectly with the existing Mira Analyzer. This means our users will be able to measure through their whole cycle with different test wands and the same Analyzer. The one-stop solution to track through a woman’s whole cycle has been long-desired. Mira is the first women’s health company that is able to provide this easy to use solution that gives women a comprehensive picture of their cycle and health.

Analyzer and Wands

How many wands do I need to buy?

You usually need 10-15 wands per cycle, depending on your cycle length. The App dynamically calculates when you need to test and reminds you about the testing days. You test occasionally at the beginning of the cycle, about once per day when around the fertile window, and twice a day at the day of ovulation. Mira’s smart algorithm saves your money and effort by learning your cycle, and only asking you to test when it is truly needed.

When do I test?

The Mira App shows green dots on a calendar screen on days that you need to test. Please, allow notifications from the Mira App in your smartphone and the App will notify you. Depends from your cycle length, testing can be every day after your period or in 2-3 days. We suggest our customers use their morning urine for the test. If that’s not applicable, you can test anytime as long as you avoid drinking any liquid for at least 2 hours before testing. The amount of liquid intake can give a negative impact on the test results. 

How do I sync with Bluetooth?

Please sync while ensuring the following steps:

  1. Make sure your Analyzer screen is on while pairing.
  2. Sometimes too many Bluetooth devices around the same area can cause competing for the same signal. Please try syncing again in another room or isolated area to see if that solves your issue.
  3. After you press “Connect Mira Analyzer” on the Mira app, keep an eye on your Analyzer as it takes 15-20 seconds for some devices for the syncing prompt on the first pairing.

It may take several attempts to complete the first pairing and please try to use the reset button at the back of the Mira device before pairing.

How do I charge a Mira Analyzer?

You can find Charging Cable for Mira Analyzer inside the Starter Kit Box and use it with any USB Power Adapter (from your phone charger or even computer USB port).

The mini USB port is going to the back of the Analyzer. Please, make sure that the MIRA logo is on top when you plug in.

The standard USB port should be inserted into a power adapter. It looks elegant but can be confusing. Don’t worry! Make sure the four small metal pieces on the charging cable must face the metal pieces you can see inside the USB port.

The Analyzer’s screen will become green and show you that it’s charging. If not, please, check that you inserted mini USB and USB ports as required.

Please see the video below and please make sure the four small metal pieces on the charging cable must face the metal pieces you can see inside the USB port. 


Why do I have Mismatched date in my App and Analyzer?

The mismatched date usually happens after the device ran out of battery and restarted. You can try to pair your device with your phone, it usually will sync the time and date with your phone. Please let us know at support@miracare.com if the issue still exists after you try.

What does None / Low / Medium / High mean?

The LH level may have inter-cycle and inter-woman variabilities. The pattern of curve is more important the absolute value. When ovulation happens, you should see a sudden increase of LH concentrations, although the peak value can vary greatly. Ovulation can happen after Medium or High LH Surge.

What does Fertility Score mean?

According to medical standards, ovulation happens 14 days before the beginning of the next period. Mira App predict fertility score based on cycle length that you entered. However, cycles can vary from woman to woman. Please, test every day when you see a green dot in App’s calendar and track your quantitative LH level. When ovulation happens, you should see a sudden increase of LH concentrations, although the peak value can vary greatly.

Irregular cycles and PCOS

Can I use Mira if my cycles are irregular?

Yes! With Mira you can see your actual hormone concentrations. Even with irregular cycles, you will be able to see when ovulation happens as long as you ovulate. You may need to test a bit more frequent than women with regular cycles, but you should be able to find your ovulation.

Is Mira PCOS-friendly?

Yes! There are many women with PCOS who use Mira to track their cycles. Mira is different from all other OPKs because Mira gives your actual hormone concentrations. With PCOS, elevated LH is usually common, and OPK will give you positive all the time. With Mira you can see your actual hormone levels and curve even your baseline LH is high.

I don’t know my cycle length, what do I need to enter?

You can enter your average or any number. The App will notify you when to test and adjust after the first cycle. You might need to test every 2-3 days and twice per day when LH surge occurs.
