Get to know your cycle and identify when you’re most fertile with clear results using our Ovulation Test. Find out whether you’re pregnant up to 3 days before your missed period with our Pregnancy Test.
Stix ovulation tests are over 99% accurate with FDA-cleared, OBGYN-approved technology.
Ovulation tests predict when you are ovulating — AKA when your ovaries release an egg and you’re most likely to get pregnant. This test measures for high levels of luteinizing hormone (LH) in your pee. LH is a hormone that surges 24-48 hours before you ovulate. You’re the most fertile on the day of the LH surge and the day after.
Before we get into the nitty gritty, everyone has a different ovulation window, and your test will come with clear, easy-to-understand instructions that lay testing dates out for you. Think of your usual cycle length, AKA the number of days from the first day of your last period to the first day of your next period (period tracking apps are a great way to get this info). Based on this number, refer to the chart in your instruction packet to determine your best day to test. For example, if the first day of your last period was the 1st and your cycle is usually 28 days long, you should start testing on the 12th.
Whether you're trying to conceive or you have irregular periods and want some peace of mind, Autoship your Stix for ultimate convenience. You can set your frequency and cancel or pause your Autoship at anytime. We'll send you an email before each order ships and another with tracking info.
Over 99% accurate.
Stix can detect hCG at 20mIU/hCG, or about 7 to 10 days after ovulation. For the best results though, we do recommend taking the test at least three days before your missed period or 19 days after you had sex. Your levels of hCG increase every single day so the longer you wait to test, the stronger the results will be.
If you were recently pregnant or are taking a drug that contains hCG (such as Pregnyl, Profasi, Pergonal, APL) you can get a false positive result. Alcohol, birth control pills, antibiotics, and painkillers will not affect results.
In general, read instructions of any drugs you are taking. Some medical conditions, like ovarian cysts, can cause false positives.
3 days before your missed period, or 19 days after you had sex. Your levels of hCG increase single day so the longer you wait to test, the stronger your pregnancy test results will be. If you do decide to test early, test first thing in the morning, before drinking any water. Stix tests are over 99% accurate on the first day of your missed period.
When you get pregnant, your body starts to produce a hormone called human chorionic gonadotropin (hCG). Stix pregnancy tests detect hCG in your urine, determining if you are pregnant or not pregnant. Two lines on the pregnancy test means your urine tested positive for hCG and you are pregnant. Just one line means your urine tested negative for hCG and you are not pregnant.
We believe in privacy above all else. Your Stix tests are delivered in a plain envelope, with no reference to Stix or pregnancy tests (not even on the return address). The envelope is small enough to fit into a mail slot, so no signature is required. Once you check out, you’ll receive an order confirmation, tracking information, and delivery updates.
