If you’ve been trying to track your ovulation, it might feel like finding your fertility window is a mystery you’ll never solve. At-home ovulation predictor kits are a great starting point, but they are just one piece of the puzzle. To increase your odds of conception, it helps to combine technology with an understanding of your body’s natural signals.

During ovulation, an egg is released and only stays viable for just 12 to 24 hours, so it’s important to learn when this occurs in your cycle.

How Ovulation Predictor Kits Work

Every brand of at-home ovulation predictor kit has its own directions, so it’s important to read them carefully. These kits typically have strips that you either pee on or dip in your collected urine. It’s measuring the presence of a surge of luteinizing hormone, or LH, which rises right before ovulation. The tests have lines that darken 48 to 24 hours before your body begins preparing for ovulation, which can be five to six days. This is helpful information, but not definitive. For example, these tests detect if your body is attempting to ovulate – not if you have released an egg or not.

Many gynecologists consider this test just one tool available and suggest taking other steps, too.

3 Natural Ways to Track Your Fertility Window

Monitor your cervical mucous. This can be one of the most effective ways to track your ovulation. Right after your period, your cervical mucous will feel dry or slightly sticky. Then it changes from sticky to lotion-like. Then, one to two days before ovulation, it becomes slippery and the consistency of egg whites.

Check your basal body temperature. You’ll want to check your basal body temperature, which is your body’s lowest temperature, occurring when you wake up. To detect a change, you’ll need to take your temperature daily, first thing in the morning, starting on the first day of your period. Use a thermometer that tests to two decimal points. Right after ovulation, a rise in progesterone occurs, triggering a rise in body temperature between half to one degree. Tracking this change can confirm that ovulation has occurred.

Track your cycle length. It’s typical to have a 28-day cycle, but many women aren’t typical. A 29- or 30-day cycle is common as well. A woman’s cycle can be anywhere from 21 to 35 days. Ovulation occurs 14 days before you bleed. For someone with a 28-day cycle, that’s halfway. If you have a 30-day cycle, it will be later. This is why tracking your periods, on paper or through an app, is crucial. You need to track for at least three months to learn your average cycle length.

It’s common to learn, after tracking your period for a few months, that your cycle is not as predictable as you thought. You may find your cycle length changes by a day or two, which is significant when you’re relying on this information to either get pregnant or avoid pregnancy.

An app is especially helpful as it allows you to record everything in real time. Some apps allow you to record your cervical mucous and basal body temperature as well.

When To See Your OB-GYN

If you track these four things, pinpoint your ovulation day and still aren’t getting pregnant, it might be helpful to talk to your gynecologist. It’s possible to have a hormone imbalance, thyroid disorder or polycystic ovary syndrome or any number of other complications. These can make getting pregnant more challenging, but with the right medical care, pregnancy is more than possible.
