Clearblue Fertility Monitor Reviews

Note: Updated November 2019

I initially wrote this post after performing a thorough research and talking to women who had used a Clearblue fertility monitor.  After using the Clearblue Advanced Fertility Monitor 1 Count for myself, I thought it was time to update this post to share my experience.

I have also included Clearblue Fertility Monitor reviews from women who have tried the device. These reviews were posted to forums by users in response to women who wished to know whether the monitor worked before trying it.

My Experience with the Clearblue Advanced Fertility Monitor

I used the Clearblue Advanced Fertility Monitor in conjunction with Wondfo ovulation test strips to compare my findings.

I waited until my next cycle to set up a “new cycle” on the monitor. I had to set up the device between cycle day (CD) 1 and 4, and I was prompted to select a 6-hour testing window.

The manufacturer advised using first-morning urine, so I selected 11 a.m., which gave me a testing window of 8 a.m. to 1 p.m. The monitor indicated the days I had to test.

I have an average cycle length of 26 days, and the monitor indicated I had to perform 10 tests during my cycle. I didn’t have to take any tests after my peak days.

The monitor displayed a flashing symbol when I was approaching the end of my cycle, and I set it up for the next cycle when Aunt Flo showed up.

What I Liked about the Monitor

It was easy to set up and use. The results were also easy to read, and the 5-minute waiting time was acceptable. The monitor displayed results as “Low”, “High,” or “Peak.

Low means the user is unlikely to conceive if she has intercourse. High means the user is approaching her peak fertility and her chances of conception are increased. Peak means the user has the highest chance of conception.

Reading the results was more straightforward than with the Wondfo ovulation test strips. With the strips, it was sometimes difficult to tell whether the test line was as dark as the control line.

What I Didn’t Like about the Monitor

The results were a little frustrating during the first month. I got a lot of “High” days, even as early as CD 7 (I typically ovulate on CD 12 to 14). The Wondfo test strips were showing that I wasn’t close to ovulating although the monitor indicated otherwise.

However, after reading quite a bit, it appeared it was normal to have many high days when you start using the monitor. It takes some time for the monitor to study your cycle, and during subsequent cycles, you’ll get fewer “High” fertility days.

The test sticks were quite expensive, and a box of 30 sticks cost close to $40. Luckily, I had to use only 10 sticks per cycle. If you have longer cycles, expect to use more (up to 20 sticks per cycle).

How Does the Clearblue Fertility Monitor Work?

It tracks two reproductive hormones, luteinizing and estrogen. The device alerts you so that you know when you are likely to conceive. If you have sexual intercourse on those days, your chances of becoming pregnant are much higher.

The beauty of this type of monitor is that you can use it at home and check your fertility status daily. The information collected by the monitor is relayed to you through touchscreen technology.

I’ll describe the different models of Clearblue fertility monitors and the test sticks that have to be used with the monitors.

Clearblue Fertility Monitor 1 Count

 Clearblue Fertility Monitor 1 Count is sensitive enough to detect when your fertility is at its peak, increasing your chances for pregnancy.  The device, which is hand-held, is used together with test sticks and monitors the levels of reproductive hormones.

This Clearblue monitor surpasses most existing fertility monitors since it monitors both luteinizing hormone and estrogen. Actually, the monitor is able to identify two peak fertility days and high fertility days.

The only problem with this monitor is that you will have to buy the sticks separately if you need a refill.

The video below demonstrates how to use this monitor.


  • It provides daily monitoring of your cycle so that you do not miss peak fertility days. It is an excellent tool for those who are striving to conceive without success.
  • It monitors the main fertility hormones, including estrogen and luteinizing hormone.
  • The tool is easy to use. Just pee on the test stick and connect it to the monitor, which will display the results after a few minutes.


  • It only works when you start using it at the beginning of your cycle. Hence, if you buy it in between your cycle, you may have to wait until your cycle starts again to use the kit.
  • It is relatively expensive.

The Clearblue Fertility Monitor 1 Count is an excellent choice from Clearblue Easy. 

It has been proven easy to use and efficient for monitoring fertility hormones. However, the price is quite high, and if you need to use the kit for more than one cycle, refills can be expensive.

Clearblue Fertility Monitor, Touch Screen


The Clearblue Fertility Test Monitor, Touch Screen is an excellent tool for anyone with irregular periods. It can help you identify your peak fertile days.

The package comes with a fertility monitoring device as well as a set of test strips, which you have to use throughout your cycle.

The display, a highly responsive touchscreen, gives you all the information you need about your fertility status. Besides, it is very user-friendly.

The video below demonstrates how to use this monitor.


  • The kit comes with test sticks, which makes this model stand out. With the other Clearblue fertility monitor, you must buy the test sticks separately.
  • It gives you a high assurance due to the accuracy of the device. 
  • The touch screen is easy to use. Additionally, the device can store your data, and it gives you clear insights into your fertility status. 
  • The tool tracks the daily status of your fertility, making it is easier for you to get pregnant.


  • It is more expensive than many fertility stools. This discourages some women from buying and using it.
  • It limits you to using Clearblue products, which makes it costly if you have to use it consistently for several cycles.

The Clearblue Fertility Test Monitor, Touch Screen is an excellent tool for women who have difficulties tracking their fertility.

It is designed to give clear results within a short period. However, it will cost you a substantial amount of money.

Clearblue Fertility Monitor Test Sticks, 30 Fertility Sticks


The Clearblue Fertility Monitor Test Sticks are unmatched when it comes to conventional ovulation tests. They increase a woman’s chances of getting pregnant. The sticks detect the presence of the two primary reproductive hormones—estrogen and luteinizing hormone.

Unlike traditional methods, it is able to identify more than the two peak fertility days. Other assessment methods, including vaginal ultrasound scans and serum hormone measurements, are considerably expensive and cannot be conducted at home.

Additionally, the Clearblue Fertility Monitor Test Sticks are easy to use and are a reliable way of tracking your fertility. The pack comes with 30 test strips and and must be used with a Clearblue fertility monitor, with or without a touchscreen.


  • You get a total of 30 test sticks. These are enough for women who have short cycles; they can use these for three cycles.
  • Together with the Clearblue fertility monitors, this tool identifies the days when you can get pregnant, thereby maximizing your chances of conceiving.


  • The sticks are expensive, considering that 30 sticks cost about $40.
  • The sticks cannot be used with other Clearblue products except with the Clearblue fertility monitors described above.

Are There Any Negative Reviews of Clearblue Fertility Monitor?

Definitely! You can find some negative reviews of the monitor on Amazon

Here’s what one customer said: 

This does not work for all women. If the monitor does not detect an LH surge you will end up going through almost twenty sticks in one cycle. I want to point out that these test sticks run about $40 for 30 and if you’re taking 20 in one cycle, you’re going to be spending a pretty penny on these sticks. I had three cycles and not once did it detect an LH surge. I asked to return this item and Amazon was very gracious and willing to refund my money. If you are trying to get pregnant (or trying not to get pregnant) be aware that you might be spending a lot of money with this. I’m not saying don’t get it, but buyers need to be aware that not all women will have their surges detected.

Are There Any Clinical Studies Showing the Effectiveness of Clearblue Fertility Monitor?

I didn’t find recent studies showing the effectiveness of the Clearblue Fertility Monitor.

One study published in Fertility and Sterility indicated that the monitor was effective in helping women to get pregnant. Women who used the monitor had a significantly higher pregnancy rate during the first two cycles of using it compared with those who didn’t use the device.

In another study, it was found that the Clearblue monitor had a sensitivity of 97% and specificity of 100% in predicting ovulation. In this case, sensitivity refers to its ability to correctly identify ovulation (true positive rate), whereas test specificity is its ability to correctly identify those who are not ovulating (true negative rate).


The Clearblue line of fertility monitors remove many user interpretation errors and increase your chances of conceiving. These high-tech devices are non-invasive and user-friendly and despite their high cost, it is worth giving them a try, especially if you’re facing difficulties in pinpointing your fertile periods.
