What is the Best Way to Track Ovulation?

Recently, one of our readers asked about the best way to track ovulation to get pregnant.

While there are several methods to help you track ovulation, we believe there is no best way to do it. Each one has its pros and cons and may cost you zero to a few hundred dollars.

Available Methods of Detecting Ovulation

The ability for you to detect your fertile period is important if you wish to plan conception or practice contraception. Here are various methods that you can use to detect ovulation. Some of them cost nothing at all and only need your time and dedication.

Fertility Awareness Methods

Fertility awareness methods help you track your menstrual cycle, so you’ll know when ovulation occurs. You can use one or more of the methods below to predict when you’ll ovulate:

  • The calendar method, which requires that you chart your cycles on a calendar.
  • The temperature method, which requires that you record your basal body temperature each morning before getting out of bed.
  • The cervical mucus method, which requires that you check your cervical mucus during your menstrual cycles.


  • Can be used to plan or avoid pregnancy.
  • It is inexpensive.
  • It is safe.


  • It may be hard to accurately predict when you’re ovulating.
  • You need to use other contraceptive methods when you’re fertile.
  • It requires commitment from you and your partner.

Ovulation Predictor Kits

These kits can help you predict ovulation 12 to 36 hours before it occurs. There are different types of ovulation predictor kits: urine-based and saliva-based.

Urine-based ovulation test kits are further divided into standard, digital, and advanced digital ovulation predictor kits.


  • Depending on the tool used, these devices can help you determine your fertile window.
  • Most ovulation predictor kits are easy to use.
  • Most ovulation predictor kits have an accuracy rate > 95% when used as described by the manufacturer.


  • Some ovulation predictor kits, especially the digital ones, can be pretty expensive.
  • Some women have difficulties interpreting the results, especially with ovulation predictor tests that display results as lines.

Fertility Monitors

These devices are more advanced and can help you predict ovulation. There are two main types: urine-based and saliva-based fertility monitors.

One popular type of urine-based fertility includes the Clearblue Fertility Monitor. This monitor detects surges in estrogen and luteinizing hormone.

One common saliva-based fertility monitor is the OvaCue Fertility Monitor, which detects changes in electrolyte levels in your saliva to predict ovulation. Read our review here.

Some fertility monitors are advanced and use machine-learning algorithms to analyze your data and predict ovulation. These include devices such as the Ava fertility tracker, Mira analyzer, and Lady-Comp fertility monitor.

Fertility Apps

These apps help you track your periods and ovulation to understand your cycles and patterns.

They use an algorithm to calculate and predict your most fertile period using the data that you provide, such as your menstruation days, basal body temperature, cervical mucus, and sexual activity.

Some popular fertility apps include Fertility Friend, Ovia, Glow, Clue, Kindara, and Natural Cycles.


  • They can track your cycles and ovulation.
  • Some, such as Period Tracker, are free. Other like Clue are cheap (< $10 annually).
  • Most fertility apps are user-friendly and straightforward to use.
