Unicharm Sofy Fertility Check Sheet, 10 pcs — Japanese Fertile-Window Tracking Panty Liners
Overview
The Sofy Fertility Check Sheet is a new type of panty liner developed by Unicharm for women who are trying to conceive. You simply wear it like a regular daily liner: Sofy's biotester technology reacts to a fertility-signal substance naturally present in vaginal discharge, and a judgment window on the sheet shows lines. Two lines indicate your likely fertile timing — the roughly six-day window around ovulation when the chance of conception is higher — while one line means the sheet reacted but it is not your fertile timing.
There is no urine sampling and no extra step in your morning: put the liner on, go about your day, and check the lines — results tend to appear within 1–2 hours after discharge contacts the reaction area. The sheets are thin, soft, unscented, and individually wrapped. This product helps you track your cycle; it is not a contraceptive and does not replace a doctor's consultation or medical testing.

Who Is This For?
- You are planning a pregnancy and want an easy, discreet way to track fertile days
- You find urine ovulation tests inconvenient or stressful to schedule
- You use a period-tracking app and want a body-based signal to complement its predictions
- You prefer Japanese-quality feminine care that fits into a normal daily routine
How to Use
- When to start: Begin using the sheets about 19 days before your next expected period (a cycle app such as Sofy Be makes this easy to calculate).
- Placement: In the morning, attach the liner to your underwear so the central reaction area aligns with where discharge lands, then press it lightly through the fabric.
- Wear: Go about your day as usual. Avoid intense, sweat-heavy exercise, and do not attach a fresh sheet immediately after bathing. Reposition if it shifts after a toilet visit.
- Read the result: Once discharge has properly contacted the reaction area, lines tend to appear within 1–2 hours. Two lines = likely fertile timing; one line = not fertile timing.
- Frequency: Use one sheet per day during your testing window; when two lines appear, the recommended timing for conception is within about 0–2 days.

Cautions
- This product helps track your fertile window; it is not a medical diagnostic device and does not replace a doctor's consultation or clinical fertility testing.
- Not a contraceptive: it cannot be used to reliably prevent pregnancy, even when no fertile timing is shown.
- Urine or other moisture on the reaction area can cause false two-line readings; some users may see persistent two-line results due to individual differences.
- Results may differ from urine ovulation tests or other methods, as the measured substance is different.
- Each sheet is single-use; do not reuse. Use within your testing window for meaningful readings.
- If you have been trying to conceive for an extended period or have concerns about your cycle, consult a gynecologist.
- Store away from humidity and direct sunlight; keep out of reach of children.

FAQ
How is this different from a urine ovulation test?
Instead of testing urine at set times, you wear the sheet like a normal panty liner and it reacts to a fertility-signal substance in discharge during the day. Because the measured target differs, results may not match urine LH tests — Unicharm suggests using each method according to its own characteristics.
When should I start using the sheets in my cycle?
Unicharm recommends starting about 19 days before your next expected period. Pairing the sheets with a cycle-tracking app helps you find that start date, and one 10-pack covers the testing window of a typical cycle.
Can I rely on it for contraception?
No. The product is not designed for contraception. Even when no fertile timing is displayed, it cannot reliably rule out the possibility of pregnancy.
Is the product authentic? Where does it ship from?
Yes — all products at Tsujimoto Market are sourced and shipped directly from Japan (Kobe). Every item is verified for authenticity before dispatch.
Will customs fees apply to my order?
Import duties and taxes depend on your country's regulations and order value. Any applicable fees are charged by your local customs office and are not included in our prices.
