More for less

We’ve got you covered. This Ovulation Test Kit includes everything you need to find your fertile days. Our clear, jargon-free instructions will walk you through how to use the at-home ovulation kit. Plus, our one-of-a-kind Cycle Tracker helps keep your test results organized so you can easily identify when you typically experience your LH surge each cycle and help predict future cycles and fertile windows.

How it works

The Ovulation Test Kit includes ovulation test strips, which look to identify a hormone called luteinizing hormone (LH) that surges as your brain tells your ovaries when it’s time to release an egg.

The Ovulation Test Kit is clinically proven to identify your fertile window with over 99% accuracy, so you know when you're most likely to get pregnant.

Ditch the casing! An earth-friendlier option.

This ovulation predictor kit uses 75% less plastic than tests with casing. Plus, unlike digital ovulation tests, it produces zero electronic waste. Our ovulation prediction kits are also certified plastic neutral which means we remove as much plastic waste from nature as our products produce.

Get peace of mind with our Early Pregnancy Test Strips

Natalist Early Pregnancy Test Strips have the precision you need—they are clinically proven to be over 99% accurate.*

  • Our Early Pregnancy Test Strips detect human Chorionic Gonadotropin (hCG), one of the first signs of pregnancy.
  • The growing embryo makes hCG, which can be detected in the woman's urine after the embryo implants into the uterine wall.

Our Early Pregnancy Test Strips use 81% less plastic than midstream pregnancy tests

We actively work to reduce our footprint on Mother Earth by identifying more sustainable manufacturing processes and materials and reducing packaging waste. That commitment was the motivation behind developing our new Early Pregnancy Test Strips. Because these at-home pregnancy test strips don’t have plastic casing, they are better for the environment. Our Early Pregnancy Test Strips use 81% less plastic than midstream tests and do not produce electronic waste from batteries or other digital components.

Fertility expert and OBGYN
"“For patients trying to get pregnant, I typically recommend using ovulation tests to better understand their body and cycle. Knowing your body's fertile window and timing sex helps increase your chances of getting pregnant.”"

We do our homework. See the research behind our hCG Pregnancy Test Strips and the Ovulation Test Kit.

Natalist Early Pregnancy Test Strips are over 99% accurate.*

Our urine, early pregnancy test strips are over 99% accurate at predicting pregnancy at 3 days before the day of the missed period. 

Early on, a pregnant woman may not be producing enough hCG for the test to detect. This is why the test is less accurate the earlier you take it. hCG can only be detected in urine after the embryo implants itself in the uterine wall, which occurs between the sixth and tenth day post-fertilization. At five days before an expected period, an embryo may have just implanted and hCG hormone production may not have yet increased enough to meet the test’s detection threshold.  Early on in pregnancy hCG levels rise rapidly, doubling every two days. The closer you are to your missed period, the more reliable your early pregnancy test results will be.

At Natalist, we understand that urge to test as early as possible—we’ve been there ourselves. You get fifteen early pregnancy test strips in each box so that you can test before, and on the day of your missed period, or whenever you choose.

Ovulation test strips help identify your fertile window by detecting your LH surge.

Ovulation is induced by a surge of luteinizing hormone (LH), a hormone produced by the anterior pituitary in the brain. This LH surge, which occurs approximately 24-48 hours before ovulation, can be detected by our easy at-home ovulation LH test strips. During your LH surge, an abundance of LH is excreted in urine, which the ovulation test kit will detect and display as a positive ovulation test result.

Ovulation tests are clinically proven to be accurate in predicting ovulation.

There are lots of options available to women to track ovulation: basal body temperature (BBT) charting, cervical mucus tracking, salivary ferning, and home ovulation tests (also known as OPKs, or ovulation predictor kits). Multiple studies have evaluated the clinical accuracy of the above methods and home ovulation tests that detect urinary LH, like the ovulation test strips included in the Natalist Ovulation Test Kit, have consistently been shown to be accurate in predicting ovulation.

Timing is critical when you’re trying to get pregnant. Our ovulation test kit finds your ideal time to conceive.

Timing is everything when trying to conceive. Finding your fertile window, aka the days when you are most likely to conceive, is essential. It can be difficult to decode your biology to find the ideal time to try to get pregnant each month. If your cycle length is irregular or varying, it can feel impossible as your fertile window makes itself a moving target. If that’s you, our ovulation kit can be especially helpful—the clear readout of the Natalist Ovulation Test Kit will tell you if you are in your LH surge or not, enabling you to confidently identify when you are ovulating.

Our ovulation test strips are FDA registered.

The sale of home ovulation tests is regulated by the Food and Drug Administration (FDA) in the United States. Ovulation tests are classified as Class I medical devices, and the FDA sets regulatory standards for their manufacture and distribution and requires that all Class I device manufacturers are registered with the FDA (FDA Registered).

Commonly asked questions

Natalist Early Pregnancy Tests

How do I use these pregnancy tests?

  • Unwrap one Natalist Early Pregnancy Test Strip and hold it by the green handle.
  • Pee into a cup, and place the cup on a flat surface.
  • Dip the test strip vertically into the cup of urine for at least 15 seconds. Be careful not to let urine get above the max line when dipping the test!
  • Place the test on a flat surface and wait five minutes before reading your result. 

When should I take a pregnancy test?

Short answer: For most accurate results, we recommend using Natalist Early Pregnancy Test Strips three days before the start of your next period.

How do I know the pregnancy test is working?

The control line will turn pink to let you know everything is functioning properly with the actual test!

Are the wrappers recyclable?

Unfortunately, the wrappers are not recyclable. 

Is the box recyclable?

Our Pregnancy Test Strip boxes are made from card box material which is 100% recyclable. 

Are the tests cruelty-free?

Yes. Our tests are not tested on animals. 

Can drinking a lot of water affect your test results?

While it is super important to stay hydrated, keep in mind that drinking a large quantity of liquid in the few hours before testing can dilute your urine and cause a false negative result. If you’re testing before your expected period, we recommend that you test first thing in the morning (when your urine has a higher concentration of hCG) if you tend to drink a lot of water throughout the day.

Is this product FSA/HSA eligible?

Yes! This product is eligible for FSA and HSA reimbursement. You can either use your HSA debit card at checkout, or use the itemized receipt (which will be in your inbox after you make a purchase). Read more about submitting for FSA and HSA reimbursement here.

Natalist Ovulation Test Kit

What comes with the Ovulation Test Kit?

Each box contains 30 individually-wrapped ovulation test strips, one reusable silicone urine cup, and we’ve also included a bonus: our patent pending Cycle Tracker to easily identify your LH surge.

How do I use these ovulation test strips?

Ovulation strips are similar to midstream test sticks, only without the plastic casing. To use your ovulation test strips, pee into the cup, and place the cup on a flat surface. Unwrap one test, and hold by the purple handle. Dip the test into the cup of urine for 20 seconds. Do not pee above the max line! You can learn more about using our ovulation test strips in our jargon-free instructions.

Why are my results streaky?

Test results may appear streaky if the test was not dipped for long enough. Make sure to dip the test for the full 20 seconds.

What does a positive result look like?

A positive result is when the test line is as dark, or darker, than the control line. To learn more about interpreting your ovulation test, read here.

What days should I take the ovulation test?

It varies depending on the length of your cycle—but the short answer is seven to 11 days after the first day of your period. Learn more about your hormone levels as well as when and how to use an ovulation test here.

What is the sensitivity level (mIU/mL) of your tests?

Each ovulation strip can detect LH in urine at 20 mlU/mL. Read more in the blog post, Does Ovulation Test Sensitivity Matter?

How do I use the Cycle Tracker?

It is helpful (and highly recommended) to keep and reference your test strips in sequential order using the included Cycle Tracker. This will help you track of when you typically experience your LH surge each cycle and will also help predict future cycles and fertile windows.

Is the cup reusable?

Yes! The cup is made from silicone, which is durable and sustainable. Please wash and reuse!

How do I dispose of the ovulation prediction kit?

Please recycle the box and paper materials. The tests, wrappers, and desiccants cannot be recycled.

Is this product FSA/HSA eligible?

Yes! This product is eligible for FSA and HSA reimbursement. You can either use your HSA debit card at checkout, or use the itemized receipt (which will be in your inbox after you make a purchase). Read more about submitting for FSA and HSA reimbursement here.
