Clearblue Advanced Fertility Montior

Proven to increase the chances of getting pregnant naturally by 89%1

The Clearblue Advanced Fertility Monitor is the only monitor that tracks and stores fertility and pregnancy information. It accurately tracks the levels of 2 key fertility hormones (estrogen and luteinising hormone) and identifies your fertility window each cycle when your chances of conception are highest (the few days before and when you are ovulating, it is designed to detect more fertile days than any ovulation text)....then you can test for pregnancy to see if you have been successful.

Learn how to use the Clearblue Advanced Fertility Monitor.

Shows both High and Peak fertility days

The monitor reads the simple urine tests to track your personal hormone levels and is designed to identify all of your High and Peak fertility days. It helps you find more fertile days than with any standard LH only ovulation test, so you have more opportunities to get pregnant each cycle.

Easy to use touch screen

The simple touch screen tells you which days you need to do urine tests and allows you to set an alarm as a reminder. You can also indicate when you've had sex on a calendar and view all of your personal fertility information for the past 6 menstrual cycles on one screen.

The Clearblue Advanced Fertility Monitor

Proven to increase the chances of getting pregnant by 89%1

Tracks 2 hormones—designed to detect all your fertile days

Use to test for pregnancy— over 99% accurate from the day your period is due

The unique cycle summary chart shows your key fertility data on one screen

Daily personal fertility status

Each cycle you'll be asked to do 10 simple urine tests (maybe 20 if your cycles are long or irregular) and from these the Monitor will read your individual hormone levels. Using this information, the monitor will show your personal fertility status each day as Low, High or Peak, so you can plan ahead and maximise your chances of getting pregnant naturally.

Test for pregnancy with the monitor

The new Clearblue Advanced Fertility Monitor also enables you to test for pregnancy up to 3 days before your period is due2. The monitor will estimate when this is and you'll see a 'cycle' icon on the display, so you can find out as soon as possible if you have conceived.

How to use the Clearblue Advanced Fertility Monitor

Before you begin

  • Always read the instructions on the pack and in the booklet carefully before use. Check that the monitor is suitable for you.
  • Set up the monitor and then wait for your next period to begin before setting a new cycle and your testing window - your testing window is a 6 hour period in which you will be able to test with the first urine of the day.
  • Always start your cycle with enough fertility tests from the same LOT for at least 10 tests.
  • Only use each test once and never after the expiry date stated.
  • Only test for fertility when the monitor shows the test day screen and always within your testing window.
  • You can test for pregnancy once a day during your testing window on any day of your menstrual cycle.

Doing the test

You test in the same way whether you are testing for fertility or pregnancy. Make sure you use the right test. Fertility tests are in purple foil and pregnancy tests are in white foil.

  1. Switch on your Clearblue Advanced Fertility Monitor every morning during your testing window to see if you should do a fertility test
  2. You must always use the first urine after your longest sleep
  3. When you are ready to test, remove a test from its foil wrapper and use it straight away
  4. Put just the absorbent sampler pointing downwards into your urine stream for 3 seconds only
  5. Or, collect a sample of your urine in a clean, dry container and put just the absorbent sampler into the urine, as shown, for 15 seconds only
  6. Keeping the test pointing downwards, pull the cap off the handle and place it over the absorbent sampler. Wipe any excess urine off the test.
  7. Immediately insert the test, as shown, into the monitor's test slot and place on a flat surface
  8. Wait for 5 minutes. The screen will switch off after 1 minute, the monitor will continue to analyse the test. The test light will flash during testing.
  9. Once testing has finished, an alarm will sound. If the monitor is off, switch it back on. The screen will ask you to remove the test before displaying the result. Throw the test away with your normal household waste. Never reuse a test.

Read your results

  • Low

    Your estrogen and luteinising hormone (LH) levels are low. You are unlikely to get pregnant from unprotected sex today.

  • High

    When the monitor has detected a rise in your level of estrogen it will display High. On subsequent days the monitor looks for your LH surge. It will continue to display High until your LH surge is detected and Peak is displayed. You need to keep testing as requested by the Monitor. Every woman's cycles are unique and hormone patterns differ, so the number of High days you see will be personal to you.

  • Peak

    When your LH surge is detected the Monitor will display Peak. You will see Peak displayed for 2 consecutive days. You are at your most fertile time the day of the LH surge and the day after (normally the day of ovulation.) Occasionally, some women have an LH surge that is too low for the Monitor to detect or they do not ovulate in a cycle and therefore they don't see Peak. This is not unusual and may happen in approx. 8% of cycles. If you do not see Peak for 3 consecutive cycles, we recommend you discuss this with your doctor.

Have intercourse on High and Peak days to maximise your chances of getting pregnant naturally.

  • Pregnant / Not Pregnant

    If you have used the Monitor to test for pregnancy, your result will be displayed as shown. The Monitor is over 99% accurate at detecting pregnancy from the day your period is due. Your results will also be shown on the calendar screen.

How do I calculate the length of my menstrual cycle?


To work out your cycle length, count the day your period starts (first day of full menstrual flow) as Day 1, and continue counting through to the day before your next period starts. The number of days is your cycle length.

Did you know?

Your partner's testes are at their best when they are relatively cool. So wearing loose underwear and light trousers and avoiding hot baths can help improve his sperm production.

Ask a Clearblue expert:


My cycles never seem to be the same length, is that normal?


Many women quite naturally have a menstrual cycle that varies by a few days month to month. If you are trying for a baby, accurately identifying your wider fertility window can be an advantage. A fertility monitor will tell you the days of high fertility and peak fertility with a wider window of opportunity during which there's a chance to conceive.

Do I need to wait several days after I have missed a period before doing a Clearblue Pregnancy Test?


No. All Clearblue Pregnancy Tests are sensitive enough to detect hCG in your urine from the day your period is due. You can use Clearblue Pregnancy Tests up to 4 days before your period is due, although the pregnancy hormone levels in your urine may not be high enough to be detected. So if you test early and you get a "Not Pregnant" test result, it's recommended that you test again when your period is due. All Clearblue Pregnancy Tests are over 99% accurate, when testing from the day the period is due.
