The Clearblue Easy Fertility Monitor is simple to use, and helps reduce the time it takes to conceive your baby. Detailed view.

Test stick monitors hormones in your urine.

The screen displays three levels of fertility -- low, high, and peak (shown).

Use the "M" button to tell the monitor your monthly cycle has begun.

The monitor also comes equipped with a handy "M Button." When you press the M Button you tell the monitor that your period has started and a new monthly cycle has begun. When you press the button you also establish the six hours each day during which you can do a test. This is called the "testing window." The testing window should be set so that it is convenient for you to test the first urine of the day both on weekdays and the weekend. At the start of each new cycle you can either press your M Button at the same time as you did on your previous cycle, or if you wish, you can change your testing window by setting the M Button at a different time. Remember, your testing window must be convenient for you to test the first urine of each day.

Your Changing Fertility
This device more accurately identifies a greater number of fertile days than any other method. During the early days of your menstrual cycle, you have a low hormone concentration, i.e. low fertility. It is during these days that your chances of getting pregnant are significantly lower. At 10-12 days into your cycle, you experience a rise in Estrogen (E3G) that signals high fertility. Your chances of conceiving are increased during these days before ovulation because sperm can survive for up to five days.

During this stage -- the Follicular Phase -- a follicle containing an egg develops in the ovary. A surge of Luteinizing hormone signals peak fertility, and it is here that your chances of conceiving are at their highest. This peak moment of fertility only last a couple days, but the Clearblue helps you pinpoint this optimal moment for conception. It is at this moment that ovulation occurs, and the follicle containing the egg bursts releasing the ovum. Of course, the egg can be fertilized for up to 24 hours, therefore you have a short duration of time within which you can optimize your chances for conception. The fourteen days after ovulation is called the Luteal Phase. During this time, the remains of the follicle forms the "corpus luteum," and, again, your chances of getting pregnant are significantly lower. All of these phases can be monitor with the help of the Clearblue Easy Fertility Monitor.

Performing a Test
The Clearblue monitor is easy to use. To perform a test simply switch on the monitor every morning within your testing window and before you go to the bathroom. On the mornings when the monitor requires further information about your hormone levels, a test will be required. Tests must be performed with the first urine of the day. First remove the test stick from its protective foil wrapper and use immediately. Hold the test stick pointing downwards in your urine stream for only three seconds. This is long enough to ensure the sampling end is sufficiently wet. Keep the test stick pointing downwards, take the cap off the handle, and place it over the wet end of the test stick.

You will see a red light flashing in the test stick slot. This is the monitor checking to see if the slot is ready to receive the test stick. You should not place the test stick into the slot until the red light has gone out. Holding the test stick by the cap with cut corner pointing downwards, insert it into the slot. Push the test stick down until it lies flat and clicks in place. Once you've correctly inserted the test stick, the display will flash the test stick symbol for about five minutes while the monitor reads and interprets the information in your urine. At the end of five minutes the monitor will ask you to remove the test stick which should be thrown away. Your fertility status will then be displayed. It's that easy.
