How To Track Your Ovulation and Boost Your Odds of Pregnancy

ICYDK, ovulation is the one-day event during your fertile window in which the egg is released from the ovaries. The fertile window is a short 5-6 days when you’re most likely to get pregnant. This is when you should be having sex with your partner or inseminating yourself if you’re working with donated sperm. 

Tracking your ovulation day, and by extension, your fertile window, is an efficient, practical way to maximize sex-for-conception among our busy schedules. 

Ahead, you’ll learn how to track your ovulation in seven different ways to help you get a positive pregnancy test result. You’ll also discover how accurate each ovulation tracking method is to help you pick the best one.

How Can I Track My Ovulation Naturally? Here are 7 Different Ways

If you’re new to ovulation tracking, rest assured that it’s a natural family planning method widely practiced by women worldwide. 

Here are seven top ways to track your ovulation. 


1. Use Ovulation Predictor Kits

Did you know that your body undergoes several hormonal changes during ovulation? 

Here’s how: 

  1. Luteinizing hormone (LH) levels spike, which takes place roughly 16-32 hours before ovulation.
  2. Estrogen levels, a sex hormone, increase during the mid-follicular phase (read: egg preparation phase). After ovulation, they fall sharply.

Zeroing in on the LH surge, you’ll likely be able to predict your optimum fertility window. 

And that’s a great thing for TTC individuals since LH levels can be quickly and conveniently measured in your urine. All you need is a suitable urine test kit. 

Enter the twoplus Ovulation Pro Read. Designed to track your ovulation patterns over a 20-day period, our fertility experts help you analyze your test results to find your unique fertile window. 

All you have to do is to urinate directly onto the ovulation test strip for 5-10 seconds every day during the 20-day window. Send us a photo of your readings every 10 days and receive a personalized report at the end of the tracking period. 


How To Tell You’re Ovulating With an Ovulation Test Kit

A positive test result (i.e., two distinct, clearly marked lines) tells you that your LH levels are high, meaning that ovulation is about to occur. This lets you know the optimal time to have procreative sex.

For the most accurate results, we recommend doing the test between 11 a.m. to 3 p.m. and 5 p.m. to 10 p.m. Consecutive tests should be performed at the same time each day for consistency.

2. Consider the Calendar Method

You may find the calendar method highly effective for healthy, fertile TTC individuals with regular periods. Before you use this method, determine what’s your cycle length. 

Here’s a refresher on how to calculate your menstrual cycle:

  • The first day of menstruation marks the first day of your cycle.
  • Count forward from that day until the first day of your next period.
  • Record the number of days for three consecutive months before averaging the numbers to find your average cycle length. 


  • Month 1: 25 days 
  • Month 2: 29 days 
  • Month 3: 30 days 
  • Average cycle length: (25 + 29 + 30) / 3 = 28 days 

To determine if your cycle length is shorter or longer than the average, check out our post on irregular periods and pregnancy

Once you know your cycle length, use the calendar method to track your ovulation. 

How it works: 

As you can see, the calendar method for tracking ovulation requires some effort. You also need to commit to it for at least a few months so you can gauge your average cycle length. 

The twoplus note: The calendar method isn’t 100% effective in tracking your ovulation. It can be even less accurate for people with irregular periods. If you’re wondering how to track ovulation with irregular periods, keep on reading. 


3. Try Digital Fertility Monitors and Cervical Mucus Trackers

As millennials and Gen Zs, we are fans of digital tools to make our lives easier and more productive. The same goes for ovulation tracking. That’s why countless digital fertility monitors and cervical mucus trackers help track your period conveniently and discreetly, especially if you experience irregular periods.

Leveraging personal data, these apps utilize algorithms and data science to try and predict your fertility window. Depending on the ovulation tracking app, there are other useful features, such as personalized forecasts, health tips and insights, and tracking for health, mood, weight, intimacy, and more. 

To help simplify your decision-making process, we’ve shortlisted some of the most popular ovulation predictors that you can download and use on your smartphone or tablet.

That said, period tracking apps are not immune to data privacy breaches and personal information leaks. A 2019 study in the British Medical Journal analyzed 24 mobile health apps and found that a whopping 79% of them “shared user data” and were “far from transparent” about it.

In fact, with the U.S. Supreme Court’s decision to overturn Roe v Wade and make abortion illegal in some states, tons of American women have since deleted their tracking apps. This is to safeguard themselves from a scenario where their personal data on these apps may be used to criminalize them for an illegal abortion in court.

If you choose to use a period tracking app to identify your fertile window, be sure to read its privacy policy and terms of usage first.


4. Track Your Basal Body Temperature

Another widely used method for detecting ovulation is to keep track of your basal body temperature. This refers to the temperature of your body when you’re at rest.

When tracking your BBT for conception, follow these tips:

  • Measure your BBT first thing in the morning: Before getting out of bed, use a digital oral thermometer or a thermometer specifically designed to measure the basal body temperature. For greater accuracy, ensure you have at least three hours of uninterrupted sleep each night. 
  • Consistency matters when taking your BBT: As much as possible, take your basal body temperature at the same time every day. You can skip BBT tracking if you’re traveling or partook in alcohol the night before.
  • Chart your BBT results: Recording your results on a chart helps you see the pattern of your average basal body temperature for better understanding. If your temperature has increased by roughly 0.4 °C and stayed that way for three days, you have likely ovulated.

Consistent basal body temperature tracking can help you guess your fertile window. But the BBT method only shows whether ovulation has occurred, not when it happened.

As such, BBT chart tracking may not be an accurate way to determine your fertile window.


5. Monitor Your Cervical Mucus Changes and Cervical Position 

Changes in Cervical Mucus

The consistency, amount, and appearance of cervical mucus change with your menstrual cycle. As such, it can also be used to track ovulation. Cervical mucus typically goes from dry and sticky to more fluid and watery as ovulation approaches. When ovulation finally occurs, cervical mucus becomes wet and stretchy, resembling raw egg whites

The reason? It’s a naturally occurring biological process to help sperm pass into the cervix during sex while providing a more hospitable alkaline environment to help them survive.

Changes in Cervical Position

Another bodily sign of ovulation is variation in your cervical position. Taking note of these physical changes can help you detect ovulation.

As ovulation approaches, your cervix goes from:

  • Firm to soft,
  • Closed to slightly opened up, and
  • Sitting lower in your vagina to moving up higher

Learning how to track your cervical position changes may take some time, so you might want to consult your OB-GYN for advice

6. Look Out for Breast Tenderness and Ovulation Pain

Hormonal changes that accompany ovulation can cause your breasts to become more tender to the touch. As such, breast tenderness could be a way to confirm that ovulation has taken place. 

Some women may also experience ovulation pain, commonly characterized as a temporary sharp pain in the lower abdomen. Experiencing this pain may indicate you’re about to ovulate or have ovulated. However, in some women, the pain is severe enough to prevent intercourse.

7. Experience a Surge in Sexual Desire

Perhaps the most primal and natural sign that you’re ovulating is an increased libido. If you’re experiencing a heightened desire for sex, that’s a good indication you’re ovulating. 

Of course, this isn’t a foolproof method to track ovulation. There are, after all, multiple reasons to feel like getting it on. Also, feeling stressed, tired, anxious, or down can detract you from the surge in libido or even negate it altogether. 


Why You Should Learn How To Track Your Ovulation When TTC 

To the uninitiated, tracking your ovulation may sound somewhat clinical. But it’s actually simple and non-invasive. 


The Science of Ovulation 

Firstly, let’s go back in time and revisit the basics of biology regarding the female reproductive system: 

  • Every month, the ovaries release an egg during ovulation.
  • When sperm is in the near vicinity, i.e., deposited near or at the cervical opening, there’s a good chance the egg will be fertilized.
  • The fertilized egg then travels to the uterus and implants in the uterine lining. 
  • The egg slowly develops into a fully-formed human being in the next 10 months.

So, how do you know when you’re ovulating? When do I start tracking my ovulation? 


The Importance of Ovulation Tracking for Pregnancy Success 

Unfortunately, the human body doesn’t get an obvious signal when a mature egg is released from the ovaries. That’s why learning how to track your ovulation is so important when trying to conceive. 

Not everyone who is TTC ovulates at the same time. The exact ovulation day depends on how long your menstrual cycle is and how regular it is.

For example, you may have a relatively short cycle of 19 days that’s pretty regular. Meanwhile, your bestie, who’s also trying to get pregnant, may struggle with irregular periods on a longer cycle. 

The good news is there are tools to help you predict or detect when your body releases an egg. This way, you’ll know the optimal time to have sex and boost your chances of a bun in the oven. (Fingers crossed!)

As you can tell by now, there’s no right or wrong answer to “What is the best way to track ovulation?” After all, there’s no 100% foolproof method, and some of the options may take some trial and error to determine your ovulation day.
