It is possible to chart your menstrual cycle to determine your most fertile days for conception, and to keep an eye on your health. ovulation tests are a convenient way to track fertility, because it can be “It’s time consuming.” and difficult.

An ovulation test is a great way to know if you are ovulating or not.

Most often, ovulation tests are used to plan pregnancy. “Ovulation tests are best used when trying to identify the fertile window to conceive,” explains Lucky Sekhon, MD, an OB-GYN, reproductive endocrinologist, and infertility specialist at RMA of New York.

For those who want to get pregnant, research finds that using at-home ovulation tests may increase your chances of getting pregnant.

Sekhon says that some people might use ovulation tests to try to prevent pregnancies.

“However, this method has a high failure rate. So, if you’re interested in preventing unplanned pregnancy, I would choose a more effective and reliable form of contraception,” she says.

Ovulation test strips are a popular option in this product category, but digital ovulation tests and ovulation-tracking smart devices are also available.

The time when an egg is released from one of the ovaries is measured by ovulation tests. The egg can be fertilized by sperm.

The hormones made by the pituitary and the ovary are assessed in most ovulation tests.

Sekhon says that the ovaries are sent a signal to ovulate an egg. The hormone signal goes through the bloodstream, gets passed through the kidneys, and ends up in the urine. It means that ovulation will likely take place in the next 12 to 36 hours.

All ovulation tests use a urine sample to determine if the woman is pregnant.

Types of ovulation tests

  • LH-only ovulation tests: These tests look for the presence of LH in the urine only.
  • LH and estrogen ovulation tests: Some ovulation tests can also detect estrogen metabolites in urine. “When a developing follicle contains a maturing egg [that’s] ready to ovulate, it secretes an elevated level of estrogen, which then signals to the pituitary that LH should be released,” Sekhon explains. So, when estrogen is detected in your urine, it gives you a heads-up that ovulation is impending. This could be useful, because LH is released in pulses, and it’s possible to miss the surge if you’re only testing once per day. “The detection of elevated estrogen may be helpful to signal when you should be paying closer attention and potentially checking twice per day.”
  • Progesterone ovulation tests: Unlike the other types of ovulation tests listed here, this type of test is used after you think you ovulated, as the hormone progesterone is produced by the ovaries post-ovulation. “Some newer test strips can detect progesterone, which can serve as a nice confirmation that you ovulated,” Sekhon says.

We spoke with medical professionals about what to look for in an ovulation test to find the best one. Experts agreed that the top factors to consider are.

  • Reason for use: The tests selected for this list are suitable for planning pregnancy. They may also potentially help prevent pregnancy if used in conjunction with other more reliable forms of contraception and cycle tracking methods.
  • Budget: There’s a wide range in the pricing of ovulation tests. Price usually correlates with ease of use, so there are some more expensive options on this list. Sekhon says that, if you’re using ovulation tests simply to time sex (and not necessarily to know your cycle better), simple LH-detecting strips work really well, tend to be cheaper, and can be bought in bulk.
  • FDA registration: It’s important that any ovulation test you use meets the standards of the Food & Drug Administration. All the ovulation tests on this list are registered with the FDA.
  • Reviews: We also checked out reviews to see which ovulation tests people had positive experiences with.

“The reviewers love that the instructions on how to use the test are printed in the packet, so you won’t have to look for the box if you forget.”

Reviewers note that the test strips are more expensive than others, but they can still provide peace of mind that the baby was born.

Reviewers note that using these tests and getting a negative PdG result helped them figure out that they needed more testing.

Some reviewers find the tests difficult to understand. The PdG tests work opposite to the LH tests. Two lines mean a positive result. One bold line means a positive result and two lines are a negative result.

Since both at- home tests require you to urinate on a strip or place the strip into urine, using an ovulation test kit is a lot like taking a pregnancy test. Refer to the directions included in your kit for specific instructions.

When an egg is likely to release and when the most likely to occur are predicted by the rise of the LH.

After urinating on the test strip, it will turn a certain color or show a positive sign to indicate that a surge in LH has been detected. You can start ovulating in the next 24 to 36 hours if you are positive.

You may need to take multiple ovulation tests over the course of several days to detect a surge in LH. You may miss the surge if you miss a day of testing.

It might be difficult to know when to start testing. It depends on the length of your menstrual cycle. The average menstrual cycle is 28 days, with a variation between 21 and 35 days.

The next cycle usually begins 12 to 14 days before the first one. It is recommended to start testing 3 to 5 days before the expected date of ovulation. If your cycle lasts for 28 days, you should begin testing around day 11.

When should you start using ovulation tests?

If you have longer or shorter cycles, it can be tricky to figure out when to take an ovulation test.

“I recommend patients start using them daily at around day 10 of their menstrual cycle,” says Zaher Merhi, MD, a reproductive endocrinology and infertility specialist and the founder of Rejuvenating Fertility Center.

What time of day should you take an ovulation test?

Experts agree that taking an ovulation test around the same time each day is more important than taking them later in the day.

That said, it’s best to use ovulation tests after 11:00 a.m., according to Zitao Liu, MD, PhD, a board certified OB-GYN and fertility doctor. This is when LH levels tend to be highest.

How long after a positive test do you ovulate?

Sekhon says that if you get a positive test result, you can expect to have an egg in your uterus within 36 hours.

If you have a positive LH test, you should time sex for the day or day after.

Is there anyone who shouldn’t use ovulation tests?

“Sekhon says that ovulation predictor kits aren’t ideal for those with very irregular, unpredictable cycles. It is not very efficient if you have to check every day. People with polycystic ovary syndrome tend to have high levels of hormones.”

“Merhi says that if you are taking any medications for fertility treatments, you shouldn’t use ovulation tests unless your doctor tells you. Some medications can be harmful.”

Can an ovulation test detect pregnancy?

“If you don’t have a pregnancy test on hand, an ovulation test can also detect a baby if it’s pregnant.”

“The hormones are different, and it is true that they have a similar structure. He doesn’t recommend using an ovulation test to check for pregnant women because of the chance of false positives.”

It can be hard to choose just one test. Some have more bells and whistles, such as apps and monitors, but simple ovulation strips will get the job done.

Most of the available choices are similar in terms of quality and accuracy. The test that is right for you depends on your needs, budget and preferences.

“If you are having trouble determining your ovulation schedule or are trying to conceive but haven’t gotten pregnant yet, you should get additional help from a doctor or healthcare professional.”
