How your fertile days are calculated

Learn more on the site —> The Ovulation & Fertility Calculator estimates when you’ll ovulate by counting back 14 days from the day you expect your next period. (If your cycle is 28 days long, your next period should start 28 days from the first day of your last period.)

Your fertile window includes the day you ovulate and the five days before, but keep in mind that you’re much more likely to get pregnant during the last three days of this time frame.

See other ways to pinpoint your fertile days and increase your chances of becoming pregnant. Find out how to use an ovulation predictor kit, chart your basal body temperature, and pay attention to changes in cervical mucus.

Signs of ovulation

  • Rise in basal body temperature
  • Cervical mucus is the texture of egg whites
  • Breast tenderness
  • Mild cramps or twinges in the abdomen
  • Very mild spotting
  • Heightened sense of smell
  • Increased sex drive
  • Changes in appetite or mood
  • Bloating

Tips for getting pregnant

  • Find out when you’ll ovulate using our calculator or an ovulation predictor kit, or by tracking your symptoms.
  • Have sex every other day around the time of ovulation.
  • Start taking a prenatal vitamin with folic acid at least one month before you start trying (6 months is ideal).
  • See your healthcare provider and make sure they’re managing any pre-existing health conditions you may have. Staying up-to-date with vaccinations and regular check-ups and testing can lower the risk of complications during pregnancy.
  • Take good care of yourself. You’ll want to kick unhealthy habits like smoking and start incorporating regular exercise into your routine if you aren’t exercising already. Eating a healthy, nutrient-dense diet can help, too.

Track Your Ovulation Window with the Help of Kindara

The Kindara app is a mobile application where I can track my menstrual cycle and understand my body through the different data that is presented to me. 

It also helps me learn how calculate the ovulation period in case I want to get pregnant or avoid pregnancy. There are a lot of benefits to using the app but I’ll be discussing them in detail below. 

For now, Kindara lets me understand my reproductive health further by letting me know more about how my body works through comprehensive charts and detailed but straightforward information about my period. 

Kindara is easy to use and lets me track my ovulation period, fertility, and more. It even makes it easy to present the data to my healthcare provider thus allowing me to make informed decisions that help me take care of my body.

Record Your Fertility Signs

Kindara offers a lot of features to its users but if there is one main feature that makes the app, it’s being able to record all of the different signs and symptoms that I feel all year round. 

I can easily record my fertility signs which include the onset of my period, the cramps that I feel, my body temperature, any test results that I have, and even the days when I had sexual intercourse. 

There are no limits to what I can record on the app which gives me an idea of what my lifestyle is. I can then show it all to my healthcare provider and they can provide me with the necessary recommendations for my reproductive health.

Track All the Important Signs and Symptoms

Women’s reproductive health differs from one individual to another. Many women suffer from irregular periods while others often have painful PMS symptoms. When it comes to overall reproductive health, it is always best to track all of the important signs and symptoms that I experience. 

They can either be the usual painful cramps to a sudden increase in temperature during my period or the bloating that I feel. Whatever it is, it is best that I keep a record of it so I know what’s important and what’s unique to my own menstrual cycle. 

There are also custom fields on the app where I can write down any other notes or necessary information that I consider relevant aside from the prompts provided in the app.

Where and How You Can Download the App

You’re probably excited to learn more about what the app is all about. Before that, I’m going to teach you how you can download the app for free. The Kindara app is available to download at the Google Play Store for Android devices and the Apple App Store for iOS devices. 

Search for the name of the app on these platforms and tap “Install” or “Get” to begin downloading the app to your smartphone device. Wait until the app is fully installed before you tap “Open” to launch it. 

The app will then ask for your credentials so go ahead and provide them with the information. You can then start tracking and monitoring your period every day now that you have the app on your phone.

Sync Your Data with Apple Health and to Your Doctor

What’s great about using the Kindara app apart from enabling me to take notes of all my experiences during my period is that I also get to share it with my doctor. 

There is an option for iOS users out there to sync my data with Apple Health. This allows me to share the data with my doctors who can provide me with more recommendations on what to do. 

This is helpful especially if you have some underlying issues with your reproductive health as a woman. As someone who experiences a lot of issues during my period, I always take down notes of all the things that have happened so I can relay them to my doctor and provide an accurate assessment of my experience. 

For women who want to get pregnant, having these extensive insights into their menstrual cycle allows their doctor to be better informed about the status of their fertility and chances of getting pregnant. 

Receive Data-Accurate Predictions from the App

Kindara is one of the greatest apps that helps me track my period. It allows me to input a lot of information and data about my cycle and symptoms. 

The app then processes this data and provides data-driven predictions that will help me decide what to do next. The data shown on the app lets me be better prepared for upcoming PMS symptoms or fertility windows.

The app only uses the data or information that I have put within the app and does not follow any population averages so you’ll know it is based on your experience only and not on other women.

Connect with Other Women in the Community

Undergoing our monthly cycles can be stressful and the symptoms that go along with a menstrual cycle can be very challenging for women. 

Fortunately, Kindara offers a way for us women to connect with each other through a community within the app. I can check out various stories from women all over the world and how they can handle the stress that comes with the experience. 

Users can also share their stories and even provide some health tips on how to handle having a period even better and in a much healthier way.

This community can be a very valuable place for women to come together and share their experiences with others and not feel alone in their struggles.

Share Your Chart with Your Partner

For those who want to involve their partners in this journey, Kindara now has the option to share the data you’ve put into the app with your partner. This allows you as a couple to move forward with your decision to either get pregnant or hold off on becoming parents. 

Your partner can keep track of your ovulation period so you don’t have to do it alone. All of the information that you add to the app can be shared so both of you are aware of the timeline of your fertility cycle. This helps bring couples even closer when planning your family together.

For couples who do not wish to get pregnant, cycle tracking and understanding when PMS symptoms may arise can be very helpful to both partners in avoiding pregnancy and understanding each other.

Why the Kindara App Is Helpful for Pregnancy

Today, pregnancy and starting a family is a choice women make. Many women want to get pregnant while others want to enjoy life without having kids. 

For women who do not want to have children, it is just as important to keep track of your cycle and ovulation so that you can avoid pregnancy. 

On the other side, being able to track ovulation and fertility windows is important for those who want to get pregnant. Women can use the Kindara app to be able to time your hopes of conception. 

When you have an idea of when your ovulation window starts, you have a better idea of when you have a higher chance of getting pregnant. Couples who want to use this method are far more likely to get pregnant.

Benefits of Using Kindara

There are a lot of advantages to using Kindara. One of which is that it is very inexpensive to use. The app does not require any sort of payment to use most of its features. 

It is safe to use and does not require a lot of attention. It is also simple to use and there is no complicated interfaces to deal with. 

How to Read a Kindara Chart

Taking and recording your temperature combined with tracking and interpreting cervical mucus signs are what makes up the Fertility Awareness Method (FAM). I frequently ask my clients to track their cycles in order to monitor period health, hormonal symptoms, and timing of ovulation.

Cycle tracking is incredibly beneficial when you trying to conceive, as it provides you with information about your fertile window. And for the very same reason, it is a great resource to use when you are not trying to conceive, as it can be used as a method of contraception.

The benefits of using FAM include:

  • Using non-hormonal contraception
  • Knowing when you ovulate
  • Being aware of your fertile and infertile windows
  • Assisting you in trying to conceive (TTC) or trying to avoid (TTA)
  • Learning more about your cycle
  • Improving awareness of your body
  • Understanding your hormone fluctuations and how they make you feel

I recommend the app Kindara for recording your temperature, cervical mucus, ovulation, and additional signs and symptoms related to your unique cycle that can be tracked. This blog will help you with the basics on how to enter data and interpret a Kindara chart. For information on basal body temperature (BBT) tracking.

When using Kindara or any other cycle tracking apps, I recommend turning off or not relying on the ovulation prediction feature. These predictions are algorithm based and rely on previous cycle data to predict your future ovulation dates. The margin of error here is quite high, as we know women can ovulate on different days of their cycle every single month!

Once you have entered a full cycles worth of temperatures, your chart may look a little something like the below. Note that this is a very straightforward looking chart, I choose this one on purpose for ease of explanation. Many charts do not look like this, so please don’t worry if your chart does note look as ‘neat’ or easy to interpret as this one!

Reading the Basics

On the left hand side we are looking at different classifications of cervical mucus. This is also known as fertile mucus. You will also see colour options for no mucus or ‘dry days’ as grey, as well as menstruation which is pink. You will see these colours logged on different days of the chart, correlating with what this user noticed on that day.

The top line on this chart is the date, underneath that is the day of the week, followed by the cycle day (CD). In this chart the date and the CD are the same, which is uncommon. This is because the user’s new cycle, starting on day 1 of the period, began on the first of the month.

Along the right hand side of this chart we see the temperatures, written in Celsius.

Along the bottom of the chart we see hearts when this user has intercourse.

Coloured hearts = sex without protection

Two hearts = withdrawal method was used

Outlined hearts = sex with protection


  • Navy dots on the chart indicate temperatures
  • Broken lines indicated days where temperature was not recorded
  • Grey dots indicate ‘ruled out’ temperatures (more on this below)

Interpreting Your Chart

We can see that menstruation occurred from CDs 1 – 5 of this cycle, with the heavier days being days 1 – 3, and lighter days being CDs 5 and 6.

Cervical mucus was logged from CD 9 to CD 22. It ranged from sticky, to creamy, to egg white, and then disappeared.

Note the navy cover line sitting at 36.4 degrees Celsius. The cover line separates pre-ovulatory and post-ovulatory temperatures, and therefore our follicular and luteal phases. The temperature of this line will be different for every person, and may change month to month. To add a cover line to your Kindara chart, press and hold your finger down anywhere on your chart. A line will pop up that you can move around.

Determining Ovulation


Ovulation is detected by sustained temperate elevation. We can see this occurring from CD 21 onwards in this chart, accompanied by egg white cervical mucus being logged.

Ovulation can only be determined in hindsight, as progesterone is what makes the temperatures rise, and progesterone is only produced in abundance post-ovulation.

This means that ovulation occurs before the temperature shift occurs – which we can observe occurring on day 20 of this cycle. It is important to highlight that this is not the traditional day 14 ovulation day that is often quoted. Ovulation doesn’t automatically occur on day 14, nor the same day of each month, and cycles are not always 28 days!

All bodies are different and unique, as are our hormones.

This chart shows a luteal phase of 12 days, as we can see by the numbers written on these elevated temperatures. To have these numbers show up in your chart, double click the day your temperature first rose, and at the upper right hand corner of the app click ‘temp. shift’.


Depending on why you are tracking your cycle – contraception, conception, or simply learning more about your body – you can track as little or as much data as you like.

You don’t have to track and enter cervical mucus if you don’t want to, you may just like to start with your temperatures and see how they look over a few cycles.

Additional Tips:

The stand-alone grey dots are temperatures there have been entered that look unusually high or abnormal to the user, and were then ‘ruled out’ on the app. To rule out a temperature, go into the days data, enter your temperature, and then click on ‘questionable’. This is helpful in making your chart easier to read if you know your temperature looks unusual.

Abnormal temperatures can be due to the following reasons:

  • Interrupted sleep
  • Oversleeping
  • Different sleeping hours to usual
  • Taking your temperature earlier/later than usual
  • Shift work
  • Drinking alcohol the night before
  • Being unwell, having a fever
  • Travel
  • Certain medications

Some people may find that their temperature drops the day before or the day their period arrives. This is a very helpful sign in knowing that your period is on it’s way! We can observe this occurring on CD 32 on the chart above.

I hope you have found this blog helpful to get you started tracking and interpreting your cycle on Kindara. I have provided a lot of information and detail here, however once you start using the app yourself, things will make a lot sense to you!


Reproductive health is a very important aspect of our lives. When you want to take control of your body, you want to have the Kindara app to help you. 

With its data-driven recommendations, uplifting stories from the community, easy-to-access interface, and comprehensive data, you can easily understand what’s going on in your body.
