FAQ

Teena is programmed with a complex algorithm which evaluates your cycle by tracking your morning temperature (taken under the tongue) and knowing when you have your period. The Teena App will then display your measured temperature value and the current phase of your cycle.

You can edit your menstruation input up to 3 days retroactively. Open your Teena App and select the date you want to edit. Select the plus (+) sign and then touch one of the drops corresponding to your flow amount. Swipe down to close this screen and you will see the period confirmed in the daily details.

You can always rely on Teena. If you have to skip a measurement after a sleepless night, Teena will still display your cycle phase. Depending on where you are in your cycle, Teena will react accordingly.

The first 2-4 cycles of use are considered the learning phase. Over the course of the learning phase, Teena will come to understand your cycle and begin predicting your next menstruation with accuracy.

It is best to try and measure your temperature every day. The more days you use Teena to measure your temperature, the better Teena can learn and predict your cycles.

Before you can begin using Teena, you must first synchronize with the Teena App to activate your device and create an account. Place your thumb on the touch field (for 4 seconds) until you see a slowly flashing turquoise light, to turn Teena on. Teena is now ready to connect to the app. Open the Teena App and follow the onscreen instructions to pair your Teena. If you have already been using Teena App in Free Mode, open the Account menu and select Register, then follow the on-screen instructions.

It will take approximately 30 seconds to measure.

Teena automatically switches off after 60 seconds

Below the tongue in the pocket next to your lingual frenulum (that’s the muscle line you feel running along the underside of your tongue) and with your mouth closed. It is best to measure on the same side each morning with the sensor tip lightly touching the bottom of your tongue if comfortable.

You can start using your Teena right away.

First things first: If you feel that there is something not right, you feel sick, or you have pain, never hesitate to consult your doctor! Most people tolerate vaccinations without any problems. Sometimes, however, vaccination reactions occur: These are almost always harmless after-effects of vaccinations, which in the vast majority of cases pass very quickly. Some vaccinated people react with a slight fever (below 39°C / 102°F), aching limbs or faintness. The fever can occur only a few hours after vaccination and last up to 3 days. Such vaccination reactions are usually completely harmless and no cause for concern. As a rule of thumb: If you wake up in the morning after the vaccination and feel different than usual, for example sick or overtired, then interrupt the measurements until you feel better again.

When staying in other time zones, synchronize your Teena with the Teena app after your arrival and your phone’s time has updated. If the time difference is more than 6 hours, we recommend skipping the measurement on the same day and the following day. You can resume your measurements as usual on the day after.

That depends on whether the medication influences your body temperature or your cycle. In general, you should skip measurements while you are taking such medication. If you have doubts, contact your doctor or our support team.

In general, you should skip measurements when you are sick and while you are taking medication that can have an influence on your body temperature or cycle. If you have doubts, contact your doctor or our support team.

Store your Teena in a cool, dry location. Teena will be ready to resume use whenever you are. If you are ready for a more in depth look at your cycle and fertility, your data can be transferred to the Daysy fertility tracker. Contact your local support team for more information.

Only very few (hormone-free) medications have a direct influence on your measurements, but often the reason why you are taking medication can influence your temperature (e.g. fever or stress). Hormonal medication will influence your temperature. If you're unsure, consult with your doctor or contact our customer service.

Because Teena has an intelligent algorithm, it can compensate for the occasional missed reading. We still recommend you measure as regularly as possible so that Teena can predict your next menstruation as precisely as possible. If you have to skip measurements due to illness, Teena will get back on track once you start again.

Use a damp cloth to carefully clean the sensor of your device. You can also use a little alcohol or soap if you wish. Since Teena is not waterproof, make sure that only the sensor and not the whole appliance comes into contact with water. We recommend the following steps for cleaning: 1. Clean the sensor and tip with lukewarm water and/or mild soap before and after each use. 2. Dry with a clean cloth. These steps will reduce the number of germs or possible viruses on the surface of the device. This cleaning is sufficient for daily personal use. If the device needs to be disinfected as well, the following steps can be practiced: 1. Wash your hands thoroughly or wear disposable gloves. 2. Clean the sensor and tip (as per steps 1 & 2 listed above). 3. Moisten the sensor and tip with a disinfectant (limited virucidal), alcohol (60-80%) or isopropanol 70%. 4. Allow to air-dry (the sensor should not touch any other objects or surfaces).

Information COVID-19: We are taking precautions as necessary, with staff wearing gloves, use of Personal Protective Equipment and increased cleaning methods. All products are disinfected prior to shipping. Coronaviruses are encased viruses, meaning they are encased in a lipid envelope. All disinfectants with a virucidal (antiviral) or limited virucidal spectrum of efficacy are effective against coronaviruses. A list of all tested and approved disinfectants to fight Covid-19 is available from United States Environmental Protection Agency found here: www.epa.gov The agents listed can inactivate the corona virus, which means it loses its ability to be infectious. This can be done in different ways: · Denaturation -> destruction of the virus surface · Removal of lipids from the virus envelope -> e.g. alcohol · Impairment to the nucleic acid of the viral genome Alcohol is capable of destroying the virus shell and can often be found already in your home. Alcohol that is 60% alcohol is effective in inactivating the virus. However, 100% alcohol is not effective because only alcohol with a proportion of water allows the lipids to be dissolved from the virus envelope. An alcohol volume between 60% and 80% is therefore recommended. Isopropanol (70% )is also a suitable agent for the inactivation of COVID-19. You can learn more about cleaning and disinfection for households from the Centers for Disease Control and Prevention here: www.cdc.gov

You can edit your menstruation input up to 3 days retroactively. Open your Teena App and select the date you want to edit. Select the plus (+) sign and then touch one of the drops corresponding to your flow amount. Swipe down on the card and you will see the period confirmed in the daily details.

Teena doesn’t allow menstruation entries prior to 3 days in the past. However, you can begin recording and syncing your temperature as soon as you have activated your account on the Teena App. Teena will start tracking with your first temperature and you can explore the cycle journey and magazine articles.

Teena’s battery can last up to 7 years, possibly longer depending on use.

Teena is made from hardy materials that can normally withstand a small fall, however we recommend checking for damage and abnormal behavior. If you do not see any physical damage and Teena’s lights appear to be working like normal, then Teena is likely okay. We suggest that you keep an eye out for erratic readings, difficulty syncing with the app, or any other abnormal behavior, as these can indicate other problems.

If the device did not take your temperature, try to repeat the measurement. Make sure to hold the device still and your mouth closed while you take your temperature.

If the measuring sensor is visibly damaged, stop using Teena right away.. Please contact our support team ASAP.

Your Teena has an internal battery that will last for up to 7 years.

When the orange and turqoise lights are alternating, this means that a measurement was not successfully recorded.

No. Teena only records the first daily measurement. If you have concerns about a reading, please contact our customer service team.

Teena will store up to one month of temperature measurements between synchronizations. Synchronize with the Teena App at least once every 30 days to avoid losing the older data saved in Teena’s memory.

Low temperature values could indicate an air pocket around the sensor tip during the measurement. To get the best measurement results, be sure to the tip of your Teena sensor is making contact with the bottom of your tongue when recording your temperature.

Cramps happen, but not everyone gets cramps.

If you do have the mild pain of cramps, this will usually come on when your period is just starting. You might feel them in your belly area or your lower back area. Cramps come in waves and may feel like a dull ache or sense of pressure.

While some cramping is common and many of us do have cramps for some periods, the pain should not be so bad that it stops you from going to school or having fun with your friends.

It is normal for cycles to fluctuate. If you're unsure, feel free to contact our customer service.

Yes, that is very normal for a teen. The importance is that a good portion of these cycles are ovulatory.

Your period may look like blood, but it’s actually different to the blood you will see if you cut your finger, for example. It contains blood, but also cells and tissue and nutrients from the inner lining of your uterus. Abouy once a month your body signals to your uterus that it should let that lining go, and it lets it go out of your vagina onto a pad or into a tampon or cup. Menstruation follows ovulation - that’s when your body releases an egg - after a certain amount of days. Hormones make ovulation happen and then they make menstruation happen in a predictable process that is your menstrual cycle!

Your first period (also known as menarche) is individual to you. Your first period will likely not happen at the same time as your friends’ first periods. On average, first periods arrive for pre-teens when they’re around 12 years old. But your first period may come earlier or later.

There are a few changes you will experience before the arrival of your first period. Before you get your first period your breasts will begin to develop, you will notice pubic hair growing under your arms and around your vulva area, and you will have a growth spurt. When your first period’s arrival is getting closer you will probably see some white cervical fluid in your underwear.

If you recently started getting your periods and you have irregular cycles, don’t worry: this is normal! A major study from the World Health Organization discovered that on average the first cycle you have after your first period is 34 days. That means there were 34 days from the first period day to the start of the next period. If you’ve been taught to expect all menstrual cycles to be 28 days in length, it might surprise you when your own cycles don’t match up. But, in reality, 38% of menstrual cycles studied by WHO went on as long as 40 days. For 10% there were more than 60 days between the first and second period. 7% had a first cycle length of 20 days.

Menstrual cycles are usually more irregular in the first year or two after you get your first period. As you get older, they usually become more regular. This is because anovulatory cycles (menstrual cycles without ovulation) happen more often when you begin getting cycles, especially if you got your first period before your teens.

A great way to start preparing for your first period is to learn all about the magic of your menstrual cycle and for this you’ve come to the right place! The more you learn about periods, the more confident you will feel when you start having cycles. Knowledge is power!

Secondly, you can prepare by putting together a first period kit for yourself, with your parent, or with your friends. This should contain period care products like pads, a change of underwear, and maybe some wipes. You can carry this with you to school in your bag or if you go on a sleepover. Usually periods arrive at school because that is where you spend a lot of time! If you’re worried about leaks, you can always have an extra shirt or sweater in your locker to tie around your waist if it happens. But know that everyone experiences leaks and it’s okay!

Shopping for your period can be fun! There are four main period care products for you to choose from - pads, tampons, menstrual cups, and period panties. Pads come in different shapes, sizes and absorbencies so it’s a good idea to get a multipack at first so you can figure out your flow. Tampons also come in multipacks. With both pads and tampons, you will use several a day and throw them in the trash when they’re used. There are also menstrual cups and period panties. With menstrual cups you will empty and wash it, then use it again. With period panties, you might wear all day and then switch in the evening, putting the used panties in the laundry basket. All of these options are great for someone who has just started getting their period. You can try them all in the next few months and see which you like best. You might pick just one or decide to use two, like say a tampon and period panties or a cup and a pad.

How long your period lasts (which means how long will you actually see period blood) can be different for you than your best friend, but for most tweens and teens a period lasts, at most, 7 days. Some of those days (mainly at the start and the end) you will see very little period blood at all. Using Teena to track your period will help you to get to know how long your period normally lasts and be prepared for future periods.

No, unless you tell them, no one will know you have your period.

If you’re worried about leaks consider taking an extra shirt or sweater to school and leaving it in your locker. That way you can always tie it around your waist if you need to. But even if there are stains, no that usually they are small and not noticeable to anyone else. Otherwise, you look just the same when you’re on your period as when you’re not.

That said, feel free to tell whoever you want about having a period and feel proud!

Much less than you expect! An average period is about four tablespoons of period blood at most. Go fill four tablespoons with water, juice, or soda and put it in a glass! See, it’s not much at all.

Yes. Irregular cycles are not a problem for Teena. As your cycles become more regular, Teena will be able to more accurately predict your next menstruation. If you have questions about your unique cycle, please reach out to our team of experts.

White or off-white or transparent “stuff” in your underwear that may look streaky or be stretchy or even globby is likely cervical fluid. You will see cervical fluid before you get your first period and during your menstrual cycles.

Cervical fluid protects the uterus from bacteria from the outside. It also plays an important role in helping sperm get to the egg for conception. When we plan for a family, we can know when we’re able to get pregnant by looking at our cervical fluid.

If you notice other kinds of fluid from your vagina that is yellow or green or looks like cottage cheese, especially if you also feel itching or burning, that can be a sign of infection. If you’re concerned about this, talk to your doctor or a trusted adult.

Let your teen know that Teena helps alleviate the anxiety over when the next period will arrive. The app makes learning about her cycles and changing body fun; and she can learn in privacy, at her own pace, without feeling awkward or embarrassed. As an added bonus, the app allows positive, supportive time on their phone.

It takes around 8-10 years for a menstural cycle to regulate for a teenager.

Yes, we had a test group for 6 months. After a brief learning curve, they stayed consistent and actually enjoyed the self check in every morning

The Teena App does not collect any personal data, such as name, email address or phone number. The account is created using the Teena device serial number. If no Teena device is being used, a virtual device ID is created. During the sign-up process a recovery key is also generated and is known only to the user of the app. An account can only be logged into with the combination of device serial number (or virtual device ID) and the recovery key. In order to display the cycle phases and menstruation predictions, the temperature and menstruation data is transferred to our server for evaluation. Since we know how sensitive this data is, it is transferred in an encrypted (https) and anonymized format to our servers within the European Union, and stored there. This means that even if unauthorized third parties were to gain access to the servers, it is not possible for the data (basal body temperature, menstruation, ovulation) to be associated to a specific person. This special protection is very important to us. You can learn more about our data privacy here, https://myteena.com/us/en/legal/privacy-policy-app/

Teena app provides valuable knowledge about everything related to the female body and being a teenager. A daily display of the body temperature (if using the Teena device) is accompanied by a simplified display of the basal body temperature curve and cycle phases, as well as positive affirmations. The Cycle Journey is an animated journey through the different phases of the cycle, from the hormones released in the brain, to the egg's path from follicle to uterus, all the way to the beginning of the next period. Short magazine articles are provided to discuss the hormones and what they control, female anatomy and self-care tips for the period. The content, written by experts and illustrated in a contemporary way, helps young women develop an awareness of their body and their femininity and use it as the superpower it is.
