FAQ:

My Peak Fertility (constant smiley face) won’t go away, is the test broken?

• When your LH surge is first detected, the test will display a static smiley face and this will continue to be displayed constantly for 48 hours, indicating your 2 most fertile days.
• Don’t remove the batteries to try to reset the holder, if you do this you will break the holder and you won’t be able to use it again

I’ve done all the tests as instructed, but have not seen High Fertility. What should I do?

• There are enough test sticks in this pack for most women with regular cycles to detect their High and Peak Fertility. It is possible that if your cycle length is long or it varies, you may need to do more tests. You should use the same holder with test sticks from a new pack.
• Some women may not see High Fertility days but see Peak Fertility days only. This may be because the estrogen level is not high enough to be detected by the test, or they started testing too late. Peak Fertility results can still be relied upon and having sex on these days maximises your chance of getting pregnant

I’ve done the tests as instructed and I did not see exactly 4 fertile days, what does this mean?

• Hormone levels and cycle length vary from one woman to another and from cycle to cycle in the same woman. The number of fertile days displayed each cycle will be personal to you and some women will have more, or less than 4. In a study of 87 women, this is what we observed:

Can I test more than once a day?

For your High fertility results to be reliable it is important to only test once a day using the urine after your longest sleep.  After your first day of High Fertility is displayed, and the test starts looking for your LH surge, you can test more frequently if you would like to, but avoid excess fluid intake before testing.

Does the test start adapting to my unique cycle right from the first day of testing?

Yes, the test reads your individual hormone levels and on the first day you test in each cycle the level of estrogen will be identified. The test cannot display High Fertility on the first day you test as it needs to determine your baseline level. Subsequent tests use this baseline level and when a significant rise in estrogen is detected it will display High Fertility. The test will then display High Fertility until it detects the LH surge and Peak Fertility is displayed. If an LH surge is detected on the first day of testing, Peak Fertility will be displayed.

Can any medication or medical conditions affect the result?

Always read the manufacturer’s instructions for any medication that you are taking before doing a test. Certain medical conditions and medications can give misleading results, for example:

- you are pregnant.

• you have recently been pregnant.
• you have reached the menopause.
• you have impaired liver or kidney function.
• you have polycystic ovarian syndrome.
• if you are taking fertility drugs containing luteinizing hormone or human Chorionic Gonadotrophin.
• you are taking antibiotics containing tetracyclines.
• some fertility treatments such as clomiphene citrate may give misleading High Fertility results. Peak Fertility results should be unaffected. If you have recently been pregnant you should wait until you have had 2 natural menstrual cycles and note how long these are before using Clearblue® Advanced Digital Ovulation Test. Please check with your doctor if you are taking any medication or have any medical condition before planning a pregnancy. If you have a medically diagnosed fertility problem you should ask your doctor if Clearblue® Advanced Digital is suitable for you.
