What do banner messages in Clue Birth Control mode mean?

Understanding different messages can help you use Clue Birth Control effectively

Top Things to Know

  • Clue Birth Control is a new digital contraceptive that is 92% effective with typical use, and 97% effective when used perfectly

  • For Clue Birth Control to be effective, you need to check the banner at the top of the app before having sex that may result in pregnancy

  • When the banner is green, your risk for pregnancy is low 

  • When the banner is orange, your risk for pregnancy is high or the app doesn’t have enough information and you should use a condom if you have sex that may result in pregnancy 

  • Enter your period start dates each cycle so Clue Birth Control can predict your high and low risk days 

Clue Birth Control is our FDA-cleared, digital contraceptive that is built into the Clue app. It works by calculating which days of the menstrual cycle are high risk or low risk for pregnancy. To use Clue Birth Control mode as a contraceptive, you need to check the app before you have sex to see if it’s a high or low risk day. In order for Clue Birth Control to be effective, you need to use a barrier method such as a condom, also known as an “external” or “male” condom, every time you have sex that may result in pregnancy on high risk days. Other barrier methods such as cervical caps or professionally fitted diaphragms can also be used.

When you open Clue Birth Control, you’ll see a colored banner at the top of the screen. Reading this banner is an important part of using Clue Birth Control to effectively prevent pregnancy. When you see the color orange, it indicates it’s a high risk day or the app doesn’t have enough information to calculate a risk prediction. You should use a condom if you have sex that may result in pregnancy. When the banner is green, you are at a low risk for pregnancy if you have sex without a condom. 

Why would I see a banner message?

These are all of the reasons why you would see banner messages in the app: 

  • It’s a high risk day

  • It’s a low risk day

  • You need to enter your period start date

  • Your cycles no longer fit requirements

  • You haven’t tracked your period 

  • You’re offline

  • Technical error

  • Your period data didn’t sync

  • You need to go online for new predictions

Let's review what each of these banners mean and what you should do based on each.



It’s a high risk day means you need to use protection

When you open the app, you may see this text on the orange banner at the top of your screen: "Your risk of pregnancy today is high. Use protection."

This banner indicates that based on the period start date you entered into Clue Birth Control, there is a high risk that unprotected sex will result in pregnancy. This also means the app is working as it should. Clue Birth Control learns your personal cycle pattern from your tracked periods and uses this data to estimate your high risk days.

On days when you see this banner, you should use a barrier method such as a condom every time you have sex that may result in pregnancy. Using a male/external condom offers the most protection compared to other types of barrier methods, such as cervical caps or diaphragms. You should see this banner anywhere from 11-16 days per cycle. 

It’s a low risk day means your risk of pregnancy from unprotected sex is low

When you open the app, you may see this text on the green banner at the top of your screen: "Your risk of pregnancy today is low."

This banner means that if you have unprotected sex, your chances of getting pregnant are low. 

To be exact, based on a study of the Clue Birth Control algorithm, 3 out of 100 women who have unprotected sex only on low risk days are expected to get pregnant over the course of a year* (1). You should always use a condom if you want protection against sexually transmitted infections (STIs).

Your cycles no longer meet requirements on Clue Birth Control means you need to use protection

It's possible to see text on a banner at the top of the screen that says: "Your entered cycles no longer fit the Clue Birth Control requirements. Use protection." This means that Clue Birth Control can’t accurately predict which days are high risk for pregnancy. Inaccurate predictions could put you at a higher risk for becoming pregnant. You will no longer be able to use Clue Birth Control until you experience 12 subsequent, eligible cycles. 

There are a few different reasons you might see this banner:

  • You tracked a cycle length that is either shorter than 20 days or longer than 40 days 

  • You tracked a cycle that is more than 9 days longer than one of your previous cycles

  • You tracked a cycle that is more than 9 days shorter than one of your previous cycles

If any of these conditions apply to you, Clue Birth Control can’t accurately predict which days are high risk for pregnancy and you will need to find an alternative birth control method. 

This banner doesn't necessarily mean you should be concerned about your cycle. It's common for cycles to occasionally be shorter or longer than what is normal for you. If you have noticed unusual changes in your cycle patterns, a healthcare provider may be able to help you determine if there is an underlying reason.

You can still use the Clue Period Tracking mode to learn about your cycles and patterns, but don’t use it as contraception. The Clue Period Tracking mode uses a different algorithm than Clue Birth Control and it isn’t designed to prevent pregnancy. After you've had 12 subsequent cycles that each fall within the eligible range, you can use Clue Birth Control for contraception again. In the meantime, talk to your healthcare provider about which methods of birth control would be best for you.

You haven’t tracked your period means you need to use protection

You might see text on a banner at the top of the screen that says: "You have not tracked a period for a while. For now, use protection." 

This banner appears when Clue Birth Control predicted your next cycle should have started more than five days ago. You haven't yet entered a period start date to indicate the beginning of that cycle. In order to accurately predict your high risk days, you need to enter your period start date in the app. In the meantime, use a barrier method such as a condom every time you have sex that may result in pregnancy. 

If you forgot to track your period, enter the start date in the app. If you haven't gotten your period yet, no problem. Bodies aren't clocks and cycles can vary from month to month. Enter your period start date on the first day of your period and you'll receive up-to-date predictions that you can rely on, at that time. If you think you could be pregnant, take a pregnancy test (a urine test will provide the quickest results).

You’re offline means you can’t enter your period start date to see accurate risk predictions until you go online

You might see this orange banner on your screen if you're not connected to the Internet: "You're offline. Go online to see your risk prediction. Use protection.”

If you enter your period start date while you are offline, Clue Birth Control can’t predict your risk for pregnancy until you get online. If you see this banner, connect to the Internet and enter your period start date so that the app can update and you can receive accurate predictions. 

Use a condom every time you have sex that may result in pregnancy until you can get online again.

You need to enter your period start date means you need to use protection until you enter a correct period start date

If you have not yet entered a period start date, you'll see an orange banner at the top of your screen that reads: "You'll get risk predictions after you’ve entered your first period. For now, use protection."

You need to enter at least one period start date in order for Clue Birth Control to predict your pregnancy risk. If you remember your last period start date, track it in the app by tapping Track (+ sign) in the bottom navigation bar. If you can’t remember your last period start date, wait to enter the start date of your next period. Until you enter a period start date, use a condom every time you have sex that may result in pregnancy.

Technical error means you need to use protection until the technical error has been solved

Clue Birth Control has been tested extensively and to the highest standards. Nevertheless, as with all technology, there could be a time when for some reason, something in the app doesn't work as expected. This means you will not be able to see risk predictions until the error is solved. In this case, you'll see an orange banner at the top of your screen that reads: "There’s an unexpected technical error. To be sure you’re safe, use protection." We do this to make sure that you don’t put yourself at risk of an unintended pregnancy until the technical error is solved.

If you know you're connected to the Internet, but you still see a technical error, try to restart the app by closing and reopening it. If restarting doesn't work immediately, try again later. If you still see the technical error banner instead of a risk prediction banner, make sure to use a barrier method such as a condom every time you have sex that may result in pregnancy.

Your period data didn’t sync on Clue Birth Control means you need to restart the app

Sometimes technology does not work as expected. When you see this message: “Looks like your period tracking didn’t sync due to a technical error. For now, use protection”, it means the data you entered in the app doesn’t match the data Clue Birth Control has stored for your profile. This means it can’t make a prediction for you. If you see this message, Clue is trying to solve the problem. Close and restart the app or try again later. Use a barrier method such as a condom every time you have sex that may result in pregnancy until the app is synced correctly and gives you a prediction. 

You need to go online for new predictions on Clue Birth Control

You might see this orange banner on your screen if you're not connected to the Internet: "You're offline. Go online to see your risk prediction. Use protection.”

When you're offline, Clue Birth Control can't calculate your risk of pregnancy because it relies on an Internet connection to process up-to-date data. You need to be online to get updated and safe predictions for each new cycle. When you're not online, your predictions will remain the same. Once you are back online, your predictions will be updated as soon as you enter your next period start date. Use a condom every time you have sex that may result in pregnancy until you can get online again.

Loading screen means you should restart the app

Clue Birth Control is driven by data. The app may take a second to process all of the necessary data to make a prediction for you. If you see the loading screen, be patient and your prediction should appear. If the app appears stuck on the loading screen, close and restart the app.  

Why you need to know about these banners in Clue Birth Control  

Every type of birth control has a varying level of efficacy. No form of birth control, hormonal or non-hormonal, is 100% effective. For Clue Birth Control to be effective, you will need to check the banner message in the app before you have sex that may result in pregnancy. In this way, it works similarly to taking a birth control pill each day or putting on a condom before you have sex. While you only have to enter your period start date each cycle, it’s NOT a set-it-and-forget-it form of contraception. For Clue Birth Control to be effective, you need to actively enter your period start dates each cycle and check the app each day to see if it’s a high or low risk day for pregnancy. If it's a high risk day, you need to use a barrier method such as a condom every time you have sex that may result in pregnancy.

*In the interest of providing easy-to-understand information that empowers people to make informed health decisions, when reporting efficacy figures, Clue uses the upper bound of the failure rate’s 95% confidence interval. Clinical trial results represent an estimate of the population efficacy rate. To be conservative, Clue reports the upper bound of the confidence interval from the peer-reviewed, published clinical trial of Clue Birth Control rather than the point estimate.The clinical trial found a point estimate with confidence intervals for the typical-use failure rate of 5.8% (95% confidence interval: 3.6% - 8.1%). The point estimate with confidence intervals for perfect use failure rate was 1.0% (95% confidence interval: -0.9% - 2.9%). Therefore, the marketed efficacy rates are 92% effective with typical use and 97% effective with perfect use. The Clue Birth Control clinical trial was conducted by researchers at Georgetown University in Washington, DC, and is registered at ClinicalTrials.gov as study number NCT02833922.

Clue Birth Control will be launched in the USA in 2022. We are excited to bring Clue Birth Control to other countries soon. This will take a little more time, but we’re on it.
