It works differently to other ovulation tests
Clearblue Advanced Digital Ovulation Test works differently to other ovulation tests as it is designed to detect 2 hormones, estrogen and LH.
When it detects a rise in your level of estrogen it displays High Fertility (flashing smiley face), and will continue to display High Fertility in the following days whilst it looks for your LH surge. When your LH surge is detected, the test displays Peak Fertility (static smiley face).
5 points you need to read before use
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.
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|
|No Peak Fertility detected after High Fertility||7 (8%)|
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 avoid excess fluid intake before testing.
Don’t remove the batteries
If you remove the batteries from the holder you will not be able to use it again.
