    FDA Registered

    Evidence Backed

    100% Plastic Neutral

    GMP Certified

    Our midstream ovulation tests are clinically proven to identify your fertile window.

    Our ovulation sticks will help you get to know your body and its variations and identify your fertile window—aka the time when you're most likely to conceive.

    • Your brain releases a surge of luteinizing hormone (LH) to tell your ovaries when it’s time to release an egg.
    • The Natalist Ovulation test can identify that "LH surge" in your urine with over 99% accuracy.
    • You’re most likely to get pregnant when you have sex during your LH surge, which indicates peak fertility.
    • Our clear, jargon-free instructions will walk you through everything.

    "For my patients who like as much information as possible, I recommend testing ovulation for three to six months so they understand their own cycle and can better time sex. This helps increase the chances of getting pregnant."

    Commonly asked questions about the Natalist Ovulation Test

    How do I use these ovulation tests?

    Read more in our PDF instructions.

    When should I take the ovulation test?

    It varies depending on the length of your menstrual cycle—but the short answer is 7-11 days after your period begins.

    How do I interpret my ovulation test?

    Learn more in this article. Check out photos of real results here.

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

    The test can detect LH hormone levels in a urine sample at 25 mlU/mL. Read more in the blog post, Does Ovulation Test Sensitivity Matter?

    Do I have to pee directly on the test, or can I pee in a cup?

    You can either pee directly on the ovulation test stick, as shown in the instructions, or dip the test into a cup of urine. Either way, be careful not to pee above the arrow, on the test window!

    Where does the Natalist Ovulation Test stand?

    The Natalist midstream ovulation test is a qualitative test with a sensitivity level of 25mIU/mL. In a 2014 study of 40 volunteers, there were LH levels recorded that broadly ranged from 6.5 mIU/mL to 101 mIU/mL, with a median of 44.6 mIU/mL. A common threshold to detect LH is 25-30 mIU/mL which accommodates tracking from a baseline level (<10 - 20mIU/mL) to an identified peak or surge (>20-40+ mIU/mL).

    What does it mean if my test line never gets as dark as the control line?

    There are a few reasons you could not get a positive test one month. When it comes to your ovulation test stick, faint test lines could mean that you missed your window for an LH peak or surge this cycle, you might not be ovulating every month, or your LH levels might be <25mIU/mL (and using a sensitive test to establish a baseline and track for a peak or surge will help to identify your fertile window). Tracking your ovulation each month with our ovulation predictor tests will provide you with results to make informed decisions based on your unique cycle.

    What Does a Positive Result Mean?

    A positive result signifies the presence of an “LH surge,” indicating that ovulation is likely to happen soon. An LH surge refers to an increase in the hormone level of luteinizing hormone that plays a vital role in signaling a woman’s body to release an egg from the ovary, a key indicator of ovulation and a woman’s fertile days to get pregnant.

    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.
