Product Description


Taking conception to the next level, the Clearblue® Fertility Monitor maximizes a woman’s chances of conceiving a baby by identifying 3x more fertile days compared to traditional ovulation tests. The #1 brand recommended by OB/GYNs, this electronic, hand-held monitor tracks a woman’s personal cycle, detecting two key ovulation hormones: luteinizing hormone (LH) and estrogen. Using the two hormones, the device can pinpoint not only a woman’s 2 peak fertility days, but also 1-5 additional high fertility days prior to ovulation – for a total of up to 6 fertile days.

Benefits of Using the Clearblue Fertility Monitor

  • It has been shown to accurately predict ovulation when compared to serum hormone measurements and vaginal ultrasound scans1, but testing can be done at home and at a fraction of the cost.
  • It gives a more accurate indication of more fertile days than any other home method.
  • It’s quick, easy to use, and easy to understand. The Monitor indicates when to test and the level of fertility every day, requiring no subjective interpretation.
  • It personalizes to a woman’s cycle, storing her information for up to six previous menstrual cycles.
  • It’s natural – no drugs or invasive devices and procedures.
  • It gives advance notice of Peak Fertility, so couples can plan intercourse at their convenience.

How the Fertility Monitor Works

There are only a few days per cycle when a woman is fertile and can conceive. The following chart outlines the phases of a woman’s menstrual cycle, showing how the two most fertile days coincide with the LH surge (24-36 hours before ovulation) and the release of an egg (ovulation). These are a woman’s 2 best days to conceive a baby.

High and Peak Fertility Chart

However, it is generally acknowledged that sperm can survive up to 5 days in the sperm-supportive mucus found in a woman’s body during the fertile days of her cycle meaning there is a fertile window of typically up to 6 days: 5 days before ovulation plus the day of ovulation. Traditional ovulation tests like Clearblue Digital Ovulation Test track the LH hormone and identify a 2 day window of fertility. But the Fertility Monitor also tracks estrogen levels, which rise just before the LH surge, extending the fertile window typically up to 6 days. This extended window can help to reduce the time it takes to conceive2 as it gives more days to try, plus gives advance notice of the 2 peak days.

Testing Directions

Detailed View of Fertility Monitor

The Fertility Monitor is easy to use and gives you clear accurate results.

  1. On the first day of your period, you will press the M button to let the monitor know a new cycle has begun.
  2. Each day, you must switch on the Monitor and follow its directions.
  3. On mornings when the Monitor requires further information about your hormone changes, a test will be requested.
  4. Simply remove the test stick from its wrapper. (Test sticks are sold separately from the Fertility Monitor. The majority of women need 10 test sticks each cycle. Women with irregular or long cycles may have to use 20 test sticks each cycle.) Point the Sampling End of the test stick downward in your urine for 3 seconds.
  5. Take the cap off the handle and place it over the Sampling End of the test stick and remove any excess urine.
  6. Holding the test stick by the cap, insert the test into the Monitor’s Test Stick Slot, pressing down until it clicks into place.
  7. The display will flash for approximately 5 minutes while reading your information.
  8. After 5 minutes, the Remove Test Stick symbol will flash. Once you have removed the test stick, your fertile status will be displayed.

Testing for Pregnancy

When you’re ready to test for pregnancy, choose a brand and product you can trust. In the Clearblue Pregnancy Test Buying Guide, we outline the different features of pregnancy tests so you can feel maximum confidence throughout the entire conception process.

More about Predicting Ovulation

As the diagram above illustrates, timing is key when trying to conceive a baby. While there are manual charting and calculator methods that may be used to predict ovulation, these methods often fall short. They require tracking a woman’s typical cycle length over several months. However, every woman’s cycle is unique and cycles for any one woman can vary from cycle to cycle – making calendar-based predictions unreliable prediction as well as time-consuming. That’s why Clearblue provides a range of products to help predict ovulation without months of charting. You can learn more about predicting ovulation and which method is right for you in our Ovulation Test Buying Guide.

So, the monitor really worked for me getting to know my cycles.
After 12 months of trying I got pregnant with this monitor after only the first month of use... It WORKS!
I received NO high fertility days and jumped straight to peak on Day 17 of my cycle.

I bought this monitor after 8 months of trying to concieve. I have very irregular periods so the thought of a machine telling me when I was ovulating sounded great.

About the machine: You have to program it to start during your period. So, if you buy it in between your cycles, you need to wait until your next period to begin using the monitor, however you can program it up to day 5 on your period, meaning if you buy this and you are anywhere from day 1-5 in your menses, you can program it for whatever day between those five days you are on. If you purchase the monitor and you are on day 3 of your period, the monitor will allow you to program day 3 and start from there. For me I had a bit of trouble figuring out the programming but to be honest Im not that mechanically inclined, but I did eventually get it.

You start testing when the maching tells you to, so you won't be testing everyday. This helps because it saves $$ on the sticks. You pee on the stick in the morning (first morning urine for best results, as opposed to afternoon urine with OPK'S) at the same time every morning. There is a 3 hour window that is allowed. So if you set your clock for 7am, but you really have to pee at 5:30, you pee at that time so the urine is concentrated. The 3 hour window can go either way- before 7am or after, just as long as its the first urine. The machine will give you either a low, high or peak (with a little egg next to the peak days) reading. The instructions advise you to baby dance on high and peak days.

Now for the cons. Its pricey! The machine itself is expensive, much, much more then OPK's and the sticks are pricey as well. When you buy the machine it will come with a certain amount of sticks, but then you need to buy refills which can get costly.

I am not advising that you purchase or not purchase this monitor. I simply need to tell you of my experience if you do use it. I was very excited to find a tool that would take the human error out of reading the ovulation test sticks to determine the LH surge, therefore predicting the peak days of fertility.
I used this monitor every month for over a year with one successful pregnancy (ending in miscarriage). The very thing I liked about this tool is possibly what prevented my getting pregnant sooner. I relied too much on the accuracy of the monitor! The machine reads the stick and displays the "fertile day" sign. If there are any errors in this reading, you won't know because you can't read them yourself. You must rely totally on the accuracy of the machine. Whereas, with the simpler ovulation predictor sticks, you can read them yourself; see the line to determine if it is darker or lighter than the test line and can compare it with sticks from one day to the next.
After trying to conceive for so long, I found myself only focusing on the "prime fertile days." I didn't have the energy to "try" if the monitor didn't say I had to. I think by narrowing my target to the 2 or 3 perfect days that this machine predicted, caused me to actually miss my fertile days. I think the machine was wrong. I came to this conclusion one month when I decided to check behind the monitor by using it simultaniously with the ovulation predictor sticks. The monitor read my LH surge as day 12 and I read the sticks as surging on day 18. If I had not checked behind the machine, so to speak, I would have missed my actual peak time. By NOT paying attention to the monitor readings, I persevered and kept at it until day 18 and this was the month I got pregnant.

After almost a year of trying, I learned about this fertility monitor. My cycles are irregular, lasting anywhere between 32 and 42 days. I told myself that whether I got pregnant or not, I would write a review after trying the monitor for 3 cycles. I got pregnant on the second one!

My DH and I are both in our late 30s and I just became pregnant for the first time, with some help from this fertility monitor. After all I'd heard about pregnancy taking a long time especially with older mothers, I was anxious to get a head start after getting married recently. I had been on birth control pills since my 20s and came off them after our wedding a few months ago. At that time, my husband and I decided to wait a few months before trying to conceive, to clear any medications, vaccinations, and "cosmeceuticals"(Rx retin-A face cream, Latisse, etc) out of my system. But at that time I started taking prenatal multi, DHA, and calcium. Then last month we decided to start trying to conceive, with the help of this CBE fertility monitor.

This monitor is easy to use. Just insert 4 AAA batteries (not incl). Turn it on. Press the "m" button until you get to the current day of your cycle (you can set it on any of days 1-5). Whatever time of day you set the "m" button, that will be the middle of your 6 hour test window. So each day, you can turn on the monitor and test any time during the 3 hours before and the 3 hours after that time. I set mine at 7am so I could test from 4-10am. If you plan to travel across alot of time zones so that your test window is no longer in the morning, you can still use it within that same window (so in my case, that would be whatever local time is at 4-10am in my home time zone). Just hold your urine for at least 4 hours before testing, to simulate it being your first morning urine (hormones have more time to build up that way).

Then every morning, turn on the monitor before you use the bathroom.
