This partnership brings together Daye’s advanced at-home testing technology and Plan Your Baby’s fertility expertise.

We're offering two types of at-home testing: our vaginal microbiome screen (using our diagnostic tampon) and hormone test kits. Both give you the insights you need to understand your fertility health, all from the comfort of home. After testing, Plan Your Baby's fertility experts are there to help you make sense of your results and plan your next steps.

Your results will be analysed by Daye’s UKAS-accredited laboratory and presented in a clear, expert-reviewed report. Plan Your Baby’s fertility specialists can then interpret these findings in the context of your fertility goals and provide tailored advice or treatment options.

Yes, both Daye’s at-home testing and Plan Your Baby’s fertility consultations are available UK-wide.

Results are typically available within 3–7 working days from when your sample arrives at the lab. You'll receive everything through your Daye account, and Plan Your Baby will be ready to discuss them with you.

Not necessarily. While both tests together give the fullest picture of your fertility health, you can choose what's right for your situation. If you're unsure which test you need, Plan Your Baby's team can guide you based on your fertility goals, medical history and previous test results.

Think of it as the immune system to your reproductive tract. It contains good bacteria (lactobacilli) and disruptive microorganisms (yeasts, viruses). A healthy vaginal microbiome is one where the good bacteria keep the disruptive ones in check, preventing them from growing out of control and causing an infection. A balanced microbiome has been linked to a lower risk of vaginal infections, STIs, and reproductive difficulties.

The Daye Diagnostic Tampon makes vaginal health testing simple, comfortable, and familiar. Designed for at-home use, it collects a full sample from the entire vaginal canal — giving you more accurate results than a traditional swab. The tampon comes with an easy-to-use applicator for smooth, hygienic insertion and to prevent contamination during collection, so you can test with confidence from the comfort of your home.

Our hormone test measures 11 key markers that affect your fertility and overall health: FSH, LH, prolactin, oestradiol, testosterone, FAI, SHBG, TSH, T4, ferritin, and vitamin D. Together, these give you a comprehensive picture of your reproductive hormones, thyroid function, and nutrient levels—all things that play a role in your ability to conceive.

The test uses a clever autodraw blood device that collects a small sample without any needles or pain. Simply press the red button against your shoulder, and the device does all the work – your sample will be ready in just 3-5 minutes.

Pop your sample in the pre-paid mailer, send it off to our accredited labs, and you'll get your results in 3-7 days.

Each tablet contains 5 billion live Lactobacillus plantarum GLP3 cells, grown in organic carrot juice and free from soy, dairy, nuts, and gluten.

They're freeze-dried to stay potent, survive your gut, and reach your vagina where they're needed. No refrigeration required—just store somewhere cool and dry.
