Stix Review: Should you buy Stix at-home pregnancy and ovulation tests?

Our thorough review explores the pricing, accuracy and value of Stix at-home tests

Last Updated: Jan 27, 2021
Stix review

Home pregnancy tests have been around since the 1970s. While they were once considered revolutionary, today they’re the norm. In fact, according to an article from Harvard’s Science in the News, about 20 million pregnancy tests are sold in the U.S. every year.

The first at-home pregnancy tests changed a lot of things for women. No longer did they have to wait until they were noticeably pregnant or felt the fetus move to confirm a pregnancy. And women could test in the privacy of home.

But while the act of actually taking a pregnancy test has been private, going to the drug store to buy one can be a harrowing experience for women due to the fear of running into someone they know or being judged by the cashier.

That’s where Stix comes in. Stix was born from the idea that pregnancy tests should be affordable and easy to access and that women should have total privacy at all stages of the process. Stix also offers ovulation tests. Is Stix a good choice for you? We thoroughly tested the products and assessed their accuracy and value – you’ll find all of the details in this review.

Bottom line

Stix has taken the idea of a reliable and effective home pregnancy or ovulation test and made it more convenient and private. Although there is not a significant difference between Stix tests and those you can find at the store, having the tests discreetly delivered to your home is convenient and eliminates uncomfortable encounters. Stix tests are comparable in price to popular pregnancy and ovulation test brands, but Stix offers a bundling option that can save you money if you order multiple tests. If you are trying to conceive or experience irregular periods, a subscription or bundle will end up saving you a lot of time, frustration, and money in the long run.

Why you should trust us

Innerbody Research recently celebrated its 20-year anniversary. Over the past two decades, we have helped tens of millions of readers make more informed decisions about staying healthy and living healthier lifestyles.

This review, like all medical-related content on this website, is thoroughly vetted by one or more members of our Medical Review Board for accuracy. Additionally, we extensively analyze each health-related service we review. We evaluate the entire customer experience from signing up to the use of the product or service, and then offer unbiased, marketing-jargon-free analysis based on the latest scientific evidence and medical standards.

What does Stix do?

Stix is an online-based brand of pregnancy and ovulation tests. It discreetly delivers these products through the mail, stigma-free. Stix products are backed by OBGYNs and use FDA-cleared technology to deliver fast results that are over 99% accurate.

At-home pregnancy tests have been around for decades and allowed women to test in the privacy of their bathroom around the time of their first missed period. But having pregnancy and ovulation tests delivered to your home is a new game-changer because there are no awkward trips to the grocery store or pharmacy, eliminating the chance that you might run into someone you know or feel judged by the person working behind the counter.

Stix actually takes discretion and privacy even further by packaging its products in plain paper pouches, free of branding. There isn’t even a return mailing address. When these tests are delivered to your home, no one but you will know what’s inside the package, which is exactly how it should be.

Stix Pregnancy Tests

The Stix Pregnancy Test works the same as other urine pregnancy tests bought over-the-counter. These tests detect hCG, a hormone produced by the body when a fertilized egg attaches to the lining of the uterus. Traces of hCG begin to appear in the urine about 10 days after fertilization.

Stix tests detect hCG 7-10 days after fertilization, but the longer you wait to test, the more reliable the results are. For the most accurate results, Stix recommends waiting until three days before your expected period or 19 days after intercourse to take the test.

If you are pregnant, the hCG in your urine clings to the test, resulting in two pink lines in the window. A single line indicates that you are not pregnant or that hCG levels are too low to detect.


A one-time Stix Pregnancy Test purchase is $13, and there are two tests in each package. You can also purchase these tests in bundles, and the more you buy, the more you save.

  • Two 2-packs are 15% off, or $22.20
  • Four are 20% off, or 41.60
  • Six are 30% off, or $54.60

Stix also provides a subscription service that automatically sends you a two-pack of tests every two, four, eight, or 12 weeks. The subscription option comes with a 17 percent discount, so each two-pack costs $10.79. You can cancel a subscription at any time.

How many do you need?

Stix recommends testing as needed if you are on birth control, have regular periods, or are not trying to get pregnant. Women who have irregular periods or are actively trying to conceive should test more frequently and would likely benefit from signing up for a subscription.

Stix pregnancy tests do not expire for one to two years, and clear expiration dates are printed on the packaging. They keep for a while after they arrive, so any tests that you don’t use can be saved for a later time.

The Stix Ovulation Test

Stix added ovulation tests to their product line after customers overwhelmingly requested them. Like its pregnancy tests, Stix Ovulation Tests work the same as those available at the pharmacy or grocery store: by measuring for high levels of luteinizing hormone (LH) in your urine. LH increases rapidly in the 24 to 48 hours leading up to ovulation. Women are most fertile on the day of the LH surge and the day after.

Knowing when to take an ovulation test can be tricky and requires that you be aware of your menstrual cycle. Stix includes detailed instructions as to how to figure out the best day to test.

If you only see the control line on the Stix Ovulation Test, there is no LH surge, and you should test again in the next day or so. If the test line is darker than or equal in color to the control line, it indicates a positive result, and ovulation is likely in the next 24 to 48 hours.


A one-time purchase includes seven Stix Ovulation Tests and costs $17. As with the pregnancy tests, Stix offers a discount if you buy multiple packs.

  • Two 7-packs are 20% off, or $27.20
  • Four are 30% off, or $47.60
  • Six are 35% off, or $66.30

If you buy a single pack of seven, you pay $2.43 a test. If you bundle six, you pay $1.58 per test, which is quite a significant savings.

Stix offers a subscription option for ovulation tests, too. If you subscribe, Stix automatically sends you a seven-pack of ovulation tests every two, four, eight, or 12 weeks at a 17% discount; each pack costs $14.11, or $2.01 a test. You can cancel a subscription at any time.

How many do you need?

If you are actively trying to conceive, it is probably worth signing up for a subscription. According to the NHS, most couples will get pregnant within a year of having regular unprotected sex, but knowing when you ovulate may make it happen sooner.

Older women who are trying to conceive should also consider a subscription as fertility decreases with age. 92% of women between the ages of 19 and 26 conceive within one year of trying. For women aged 35 to 39, it drops to 82%. With a Stix ovulation test subscription, you can be prepared every month to figure out when you are most fertile and save a bit of money.

Stix ovulation tests do not expire for a few years after you receive them, and the expiration date is written on the package. You always cancel your subscription and hold onto them if it turns out you don’t need them at present.

Getting started with Stix

Stix’s website is exceptionally easy to navigate. There are only two products to choose from, but Stix does a good job of prompting you about subscriptions and bundling.

Choose either the pregnancy or ovulation test and indicate whether you are interested in a one-time purchase or a subscription. If you go for a one-time purchase, you are prompted to choose a quantity. If you choose a subscription, there is a simple drop-down menu to choose how often you want the tests delivered.

In your shopping cart, Stix gives the option to add bonuses, like an extra ovulation test for $2 or three bonus pregnancy tests for $15. The website again prompts you about the bundling discount, and you can easily change the quantity right in your shopping cart.

When you’re ready to check out, the site prompts you to sign up for an account, which is required as there is no option to check out as a guest.

You can also enter coupon codes at checkout. If you sign up for the newsletter, Stix sends you an email with a code for 20% off your first order and free shipping. The company also offers a “give and get” promotion where, if you refer a friend, you both receive a code for the 20% discount.

HSA, FSA and health insurance

Stix does accept FSA and HSA payments. Check out as normal and use your FSA card or save your receipt to submit an HSA claim. Per the IRS, ovulation and pregnancy tests are acceptable medical expenses approved for these programs.

Privacy considerations

Stix’s privacy policy is easy to find on its website. The company collects information about your web browser, IP address, time zone, and the cookies that are installed on your computer or device. It also collects information about the products and pages that you view and the search engines and terms that directed you to the site.

Stix will collect your name, billing address, shipping address, email, phone number, and payment information when you make a purchase. This information is stored securely through the site, but you can delete it if you wish. Stix uses this information to fulfill orders, screen for fraud, send information about its products and services, and to understand how users interact with the website. All of this is pretty standard for online retailers.

Stix uses Shopify to power its store and Google Analytics to optimize its site, so it does share information with both of those entities. If you want to opt out of Google Analytics, Stix provides a link in its privacy policy, which will enable you to opt out.

How we evaluate health service companies

At Innerbody Research, we customize our evaluation criteria depending on the type and nature of the health-related service. For Stix and other health services and products, we have five areas that we use for our evaluations, including:

Quality: How well does the company deliver its core service(s) to the customer? For testing services, does the company adhere to the latest and most advanced testing technologies and achieve a very high degree of accuracy? For non-testing telehealth services, is the quality of the service high enough that we would recommend it to loved ones without hesitation? If not, why not?

User-friendly: How intuitive and user-friendly is the service? Does the device/program/app/website achieve a good degree of user-friendliness for its customers?

Value: Are you getting your money’s worth? Are there any hidden costs or charges? Does the company offer discounts?

Privacy: If health data is stored, will your data be stored securely? Are payments secure?

Customer support: Particularly in situations where ‘one size fits all’ doesn’t make sense, how well does the company help to make the service ideal for you?
