Product Description

Product Description

The Clearblue Fertility Monitor identifies the prime fertility days to help women who are trying to conceive maximize their chances of getting pregnant. A non-invasive and easy-to-use device, the Clearblue Fertility Monitor consists of a handheld monitor that, along with the use of the Clearblue Fertility Monitor Test Sticks, identifies changes in fertility hormones. While most over-the-counter ovulation tests monitor the LH hormone on its own, the Clearblue Fertility Monitor tracks both LH and estrogen hormones to typically identify up to 6 fertile days — 2 days of Peak Fertility days and 1–5 days of High Fertility.


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.

After using it for a few months, I became pregnant and now have a beautiful baby boy.
This really worked wonderfully for us and it helped to take the guesswork out of figuring out the right timing.
I have very irregular periods so the thought of a machine telling me when I was ovulating sounded great.

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.

I do not work for the Clearblue company. I am a real 32 year old man. My wife and I tried for 4 years to get pregnant. She lost a tube due to an ectopic pregnancy years before I even met her. While dating, she cried and told me to leave her because she was told she could not have any children. I promised her that we would find a way. After marriage we tried for a year. She gave up in her heart, I knew it. I was considering doing the IVF thing, but first I wanted to try this product. Found it after browsing around Amazon for fertilization products. Got pregnant 2 months after using this device, and a lot of prayer. It is possible folks, just have to figure out your high peak day, and baby dance the day before and on that day and sit back. Wife didn't even think she was pregnant but when she almost blew chucks on my dashboard I knew she was. She is now 5 weeks and no ectopic pregnancy. DO NOT GIVE UP!!

I was in the same boat as many other reviewers of this monitor--I swore I would write a positive review if this monitor worked for me, and IT DID! My husband and I had been TTC for 8 months and we were getting extremely frustrated. We were beginning to worry that something was wrong with one [or both] of us, and couldn't understand why it was so difficult to conceive because my monthly cycle was regular like clockwork and I could've sworn that I knew my fertile days. On month #9 of TTC, I decided to bite the bullet and buy this monitor because of all the glowing reviews, and I figured there wasn't much to lose by trying it out. I was extremely skeptical at first, and definitely did NOT expect the monitor to work on the first month... boy did it prove me wrong! Turned out that I was ovulating slightly earlier than I had expected, and this monitor helped me catch that. I got pretty standard results--several high days and 2 peak days, followed by another high day.... and then BAM, about 2 weeks later I missed my period and got that much-longed-for BFP! I thought the initial results were a fluke--how could the monitor "know" my cycle so quickly already? I don't know how this little machine does it, but it's amazing.... this monitor's results might have coincided with more conscientious BBT charting and CM observations on my part, but it was definitely our little good luck charm.

The instructions were easy to follow--just decide what time you want to [or are most likely to] pee each morning within a 4-hour window, and press the "m" button on the monitor at the time that would be in the middle of that 4-hour window. I pressed my m button at 7AM, so my 4-hour window to pee each morning would be between 5AM and 9AM.
