Peak Fertility displayed constantly for 48 hours

Peak Fertility is displayed constantly for 48 hours after it first appears

You cannot do another test while Peak Fertility is shown, as the holder will not be able to read it.


4 or more fertile days

The number of fertile days you see is personal to you

Not all cycles are the same. The number of fertile days you see is personal to you. Every woman’s cycles are unique and hormone patterns differ. In a study of 87 women, this is what we observed:

Number of High Fertility days before Peak Fertility Number of Women
0-4 66%
5-9 25%
10+ 1%
No Peak Fertility detected after High Fertility 8%
TOTAL 100%


More than 9 fertile days

Seen more than 9 High Fertility days?

If you see more than 9 High Fertility days you may wish to stop testing this cycle.
- If you started testing on the correct day for your usual cycle length and you see 9 or more days of High Fertility, it is unlikely that you will see Peak Fertility in this cycle.
- Occasionally some women have an LH surge that is too low for the test to detect or they do not ovulate during a cycle and therefore they don’t see Peak Fertility. This is not unusual and may happen in approximately 8% of cycles. If you do not see Peak Fertility for 3 consecutive cycles, we recommend you discuss this with your doctor.


Test once a day

Only test once a day until you see High Fertility

For reliable High Fertility results you must use the urine from after your longest sleep. When you have seen High Fertility you can test more often, but drink normally and it’s important not to urinate for 4 hours before testing again.
