Knowing more about your FSH levels can help you spot hormonal changes that affect fertility and perimenopause, without the bloodwork.

One at-home test.

Early insights into fertility

and perimenopause.

Your hormones may be changing—get a read on your FSH levels at home.

Noticing sleep changes, irregular cycles, and mood shifts? They could be signs of perimenopause and, along with rising FSH, are early markers the transition. Perimenopause doesn't happen overnight—it's often gradual and can take years. And early insight into hormone changes (like tracking rising FSH) can help you feel informed and in control.

Your hormones may be changing—get a read at home.

Perimenopause is a gradual shift, not an overnight event. Symptoms—like irregular cycles, sleep disruption, or mood changes—can begin years before menopause. Early insight into hormone changes can help you feel informed and more in control.

— How it works

What the Results mean

Test at home in under 10 minutes

Dip the strip in first‑morning urine on cycle days 3, 4, and 5. Repeat next cycle.

Compare to reference chart

Each shade corresponds to an FSH range. No app needed.

Understand your FSH reading

  • ≤ 10 mIU/mL:

    Normal range

  • 10–25 mIU/mL:

    Elevated—possible diminished ovarian reserve

  • 25+ mIU/mL:

    May indicate perimenopause transition

  • 50+ mIU/mL: Typically menopausal range

Test over multiple cycles to detect patterns

Because hormones can vary, we recommend taking the test several times (on days 3, 4, and 5 over 2 cycles). If the majority are showing elevated or high FSH levels, check in with your doctor for diagnostic testing.

My doctor dismissed my concerns saying that I am young, and wouldn’t sign off on fertility testing. I am so glad that I bought these and confirmed my concerns were valid. I made an appointment with a different doctor to hopefully get referred to a fertility specialist.

I'm 36 and I was a little concerned about this test result. I was happy to see the same result over the 2 cycles. I haven't done a lab test yet for FSH but I do feel confident that it should come out good. Thank you Bird and bee for giving me this piece of mind.

FAQs

No—clinical definition of menopause is 12 full months without a period. This is a screening tool—not diagnostic

No—FSH tests egg quantity, not quality or fertility potential. A high FSH can suggest diminished ovarian reserve (which is important for your reproductive potential), but it doesn’t predict your ability to conceive.

Anyone curious about ovarian reserve—especially those noticing cycle shifts, planning for pregnancy, or wanting to be proactive

Hormones vary. That’s why testing over two cycles is recommended. If more than one test shows elevated or high FSH, consider speaking with your doctor.

Yes, our Bits are safe for sensitive teeth. We use Nano-hydroxyapatite in our Fluoride-Free formula, a mineral that's been proven to strengthen and remineralize enamel and help fight sensitivity.

We also recommend talking to your dentist about Nano-hydroxyapatite or when making any changes to your oral care routine.

Follicle-stimulating hormone (or FSH) is just one of the several hormones that affect your body's functions, including the reproductive system. As its name suggests, the main role of FSH is to stimulate the small follicles (the sacs that hold the eggs) early in the menstrual cycle so that one will be recruited and released ahead of ovulation. FSH is also a marker of ovarian reserve (letting you know more about how many eggs you have left) and fewer eggs could mean you’re closer to menopause which marks the end of your reproductive years.

This test does not diagnose perimenopause, menopause, or fertility status. Elevated FSH levels alone are not diagnostic. Always consult a healthcare provider before making medical decisions.
