Description

"Trying for a baby? It can feel like a guessing game at times, so knowing your most fertile days each cycle is a must. With the Clearblue Fertility Monitor with Touch Screen (Monitor de fertilidad Clearblue con pantalla tactil), you can identify which days you’re most likely to get pregnant. Clearblue Fertility Monitor Test Sticks are designed for use with Clearblue Fertility Monitor with Touch Screen (Monitor de fertilidad Clearblue con pantalla tactil), which is designed to detect all your fertile days[1]. Each home fertility test refill pack includes 30 individually wrapped test sticks. Most women will need 10 tests each cycle, while women with irregular or long cycles may have to use 20 tests each cycle. They must be used with the Clearblue Fertility Monitor (sold separately). The monitor works by tracking both estrogen and luteinizing hormone (LH) to typically identify up to 6 fertile days. It tells you when to test your urine and displays your daily fertility status as Low, High, or Peak. Its easy-to-use touch screen also lets you record your period dates and when you have sex and can compare up to 6 cycles in either a monthly calendar or graph for side-by-side comparison[3]. [1] Number of fertile days will vary. In a German study of 149 cycles, Monitor results correlated with serum hormone levels & ultrasound-observed ovulation. [2] Clearblue Ovulation assay showed 97% agreement with ultrasound-observed ovulation. Behre HM., et al. Human Reproduction (2000) 15: 2478-82. [3] Completed cycle data if available." From the Manufacturer To use the Clearblue® Fertility Monitor – the 1 brand recommended by OB/GYNs – to maximize your chances of getting pregnant, you will need to purchase the Clearblue Fertility Monitor Test Sticks separate from the device. Clearblue Fertility Monitor Test Stick packs include 30 individually wrapped test sticks. The majority of women will need 10 test sticks each cycle. Women with irregular or long cycles may have to use 20 test sticks each cycle.About the Clearblue Fertility MonitorTaking 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. 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 MonitorIt has been shown to accurately predict ovulation when compared to serum hormone measurements and vaginal ultrasound scans2, 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 WorksThere 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.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 DirectionsThe Fertility Monitor is easy to use and gives you clear accurate results.On the first day of your period, you will press the M button to let the monitor know a new cycle has begun.Each day, you must switch on the Monitor and follow its directions.On mornings when the Monitor requires further information about your hormone changes, a test will be requested.Simply remove the test stick from its wrapper. (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 downstream in your urine for 3 seconds.Take the cap off the handle and place it over the Sampling End of the test stick and remove any excess urine.Holding the test stick by the cap, insert the test into the Monitor’s Test Stick Slot, pressing down until it clicks into place.The display will flash for approximately 5 minutes while reading your information.After 5 minutes, the Remove Test Stick symbol will flash. Once you have removed the test stick, your fertile status will be displayed.Low fertility = very small chance of conceiving High fertility = increased chance of conceiving Peak fertility = highest chance of conceivingTesting for PregnancyWhen 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 OvulationAs 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.1 Behre HM et al.

Size: 1 Count (Pack of 1) Style: 1 Fertility Monitor
Okay. :-) This is a long review. For those trying to get pregnant: I used this monitor along with the ClearBlue digital OPK, some cheap LH OPK strips from Amazon (blue box with colorful words about pregnancy), a pocket microscope to track ferning, and a BBT thermometer to track basal temp along with the Period Tracker app (pink flower app) and my FitBit Versa women wellness app section. EACH METHOD MATCHED. Everything down to my predicted ovulation on my tracking apps (was off by a day on both) lined up with an LH surge and peak fertility. I believe this can be trusted to help get pregnant, but do maybe 3-4 cycles—probably by cycle 4 you will be pregnant! For those just trying out tracking methods: This device is a powerful asset to the tools out there now for at home tracking of LH surges and estrogen level increases. I wouldn’t use it by itself because it may read incorrectly or display an error, which would have been EXTREMELY disheartening if I were trying to get pregnant and that was my only testing method—this thing is expensive, BUT THE TEST STICKS ARE ROBBERY. I was dumb and bought mine at CVS because they weren’t in stock anywhere else and I had to test the next morning so I couldn’t order them in time from Amazon—THEY WERE $80! I digress.... Anyway, the monitor stores your info for 6 months then deletes your first month to make room for month 7, so keep that in mind. It was accurate with my other tracking methods but was a little annoying to use because you can only set it up to test ON DAYS 1-4 OF YOUR CYCLE and your testing window of 6 hours CANNOT BE CHANGED ONCE YOU CHOOSE IT. Choose your window wisely and take into account if you sleep in on the weekends, as I missed my window by 30 minutes once and almost missed it a second time. For those wanting it as contraception: I hope this was your ultimate last resort or you’re rolling in dollars, because this thing plus the test sticks are expensive. You would DEFINITELY be better off buying the cheap LH test strips on the market and maybe using 1 or 2 other methods that are free to you (checking cervical position/texture and cervical mucus). Otherwise, this is just another tool to help you keep track of your lady cycle (did I mention it’s expensive...?) and it is wholly unnecessary when condoms and Plan B’s exist. It is nice to have and it has an easy-to-read calendar which makes avoiding your fertile days a breeze, but keep in mind that just because your fertile window has passed, it doesn’t mean you can’t still get pregnant. Use caution when trying NOT to conceive—these products are mostly for those wanting to become pregnant so they aren’t on your side to begin with! Overall it worked for me, I was thrilled with the results and I believe this will help me get pregnant when I am ready. It matched other OPK tests, my saliva ferned in time with the results, and my body temp increased as I approached ovulation and went back to normal after. The test window was a pain though. However, if you use the dip method (essential if you’re using multiple tests) it is potentially less annoying and you probably won’t waste a stick because I used the monitor sticks with the ClearBlue Advanced Digital monitor and they matched. Couldn’t use the Digital sticks with the monitor, though, even though they seem the same. But if you’re out of options except a fertility specialist and the money is worth it to you, GET THIS THING. It worked for me. (33 day cycle, no ovarian issues). I don’t regret buying it, but I also had a very positive first experience with it. It arrived right on time for me to set it up on day 4 of my cycle. ... show more

  • Definitely need to have sex on peak days....I’m pregnant after 3 cycles.
Size: 1 Count (Pack of 1) Style: 1 Fertility Monitor
I’m 37 and it took me 3 months to get pregnant. I already have a 5 year old. I recently suffered a stillbirth at 23 weeks (back in April 2017) and after trying to get pregnant in August with no luck, figured I would go back to Clearblue for help via their fertility monitor. To get pregnant with my 5 year old, I used this monitor (older version) and got pregnant on the second cycle. With my current pregnancy, I believe it took 3 cycles to get pregnant because the previous 2 cycles I did not have sex on the peak days. The cycle I got pregnant, had sex on the first peak day. My advice to couples is that this monitor is a good tool to have but ensure you have sex on either one of the peak days or both to maximize your chances. Also, it’s a bother but try to chart your basal body temperatures. It will help you to ascertain whether what the monitor has told you is correct. A mistake that I had made with the monitor was to set the testing window at 5am - 11am which meant I could test anywhere between those hours. The problem with that is, if your LH surges at let’s say 1pm, you would have missed your opportunity (if you have a short surge) and by the time you test the next day, the monitor may not show the peak (since the LH surge was short). So, what I did the cycle I got pregnant was to change the testing window to start at I believe 12pm and I would test at 2pm instead. That gives the monitor the opportunity to better catch the LH surge. The monitor is costly and the sticks are as well but totally worth it in the end. I also used the clear blue digital to get my positive. Good luck to all couples trying to conceive. Be patient, be positive and definitely take your prenatals when trying to conceive. ... show more

  • Happy With My Purchase
Size: 1 Count (Pack of 1) Style: 1 Fertility Monitor
My husband convinced me to buy this "dumb" monitor (no apps, no wifi connection) and I'm honestly glad that's what we went with in the end. This does the bare minimum needed and it does it perfectly well. We ended up getting pregnant in only three months! Some "downsides" - you cannot change the testing time frame until your next period, but I think that's just a practical need for any fertility testing. It also is annoying to have to wait 5 minutes to see the results, but not too bad. As a warning, I did have trouble getting a steady result the first month I was off birth control. The instruction manual warned that it can take up to two months to get accurate results after stopping birth control. Just something to keep in mind for any fertility testing! ... show more

  • Reliable and easy to use fertility test sticks
Size: 30 Count (Pack of 1) Style: 30 Fertility Tests
These Clearblue fertility monitor test sticks have been a huge help in tracking my cycle accurately. They’re easy to use with the monitor and give clear, reliable results every time. I love that the system tracks two hormones, which makes it feel more precise than basic ovulation tests. It’s reassuring to know exactly when my most fertile days are, and it definitely helps take some guesswork out of trying to conceive. The box has enough sticks for several cycles, so it’s a good value too. Everything came well packaged and in perfect condition. Overall, these are excellent test sticks that work exactly as promised and make fertility tracking simple and stress free. ... show more

  • Just plain difficult and not user friendly and LOST 3 MONTHS OF DATA ON MY 1ST PEAK DAY :'(
Size: 1 Count (Pack of 1) Style: 1 Fertility Monitor
To be honest I hate this monitor, its cool they updated the look but i hate how restricting it is, i can only do what they say when they say. I cant change the time for day light savings so its an hour off and it says i have to start a new cycle to change it... LAME. The test window is stupid too... when i get up and want to test let me freaking do it... but no it says i have to wait until my "test" window... i hate that. To alter anything you have to start a new cycle... there should be a way to change dates, like for me i forgot to enter the first day of my period so it will only allow me to count the 2nd day as my "1st" day in the monitor so already numbers wont be correct... the next thing that i hate is how hard it is to open the battery compartment up. I finally just pried it off and leave it off since the batteries are in there snug and i don't have it around anything liquid. The analysis part takes forever and to be honest i highly doubt its doing anything other than reading if there is 1 or two lines and how dark they are which you could do that yourself just by looking and skip the monitor all together. It may seem cool it keeps the data in the system but the fact you cant change anything really sucks. not all of us have regular periods or perfect cycles or heck were human we mess up or start it the wrong day. I feel like for the price and what it does it leaves a lot to be desired. There are lots of apps you could use for free on your phone for tracking and I don't feel this is worth the price or the effort. I think the regular OPK sticks would work just as well (unless you have pcos and cant get a good reading with them) but they really should make it more user friendly and add in more options... They also should add the option to have a chargeable battery in it and just plug it in to charge it. I wish i had saved my money but its to late now Im going to use the box of sticks i bought and see if it at least helps me get pregnant... UPDATE: 05/01/2017 so today i go to take a test but when it was time to insert it i turned it on and just before i entered the stick in it went black and it self restarted and was asking me to create a new cycle... I almost cried TTC is already hard but now several months of data is just gone and i cant even use the stick I mean i can see the lines and it should be a peak day but its not just the test here its also that the device is supposed to record cycle data so it gets your averages and so on... and now that's lost I wont miss the day we will still know when we should BD but it really sucks I paid over $100 for this thing plus like $80 bucks at least on sticks for it and now the info is just gone... so now i either can start over or use nothing... This just makes me so freaking mad and heartbroken I really wanted this to work but so far it really hasnt. Its great for those with a properly working device but if you get a messed up one or god forbid it doesn't mess up until right after its to late to return then you could potentially be out a few hundred bucks and have nothing to show for it. They really should make an sd slot to store info and also have a manual mode where you can go in and manually enter past cycle data just in case your info is lost... I have bought all kinds of random TTC things and sadly this one (that I wanted the most and couldnt wait to get) has been the worst and it really RELLY upsets me now my cycle data is just gone. Anyone out there with irregular cycles or other issues knows just how precious this info can be and after several months watching the divice start to predict info was cool but now im back to square one and today should be day 1 of my 2 peak days so i cant even do anything until i start a new period... I would much rather pay twice as much for a device that has a lot more options and the ability to save, export and manually enter data. as well as let you decide when to start a cycle (i realize they believe this will help accuracy but starting in the middle or a few days in if you enter period data should be fine and it allows the user to use the divice right away... the point is collective data anyway) this is by far the most frustrating divice i have used i think honestly im going to call them and see what they tell me and if i can possibly get a fixed device i may try again but if not im going to toss it and cry beecause while $104 may not be a huge amount its also not something most of us can afford to just toss out so losing that and the money i put in to sticks kind of makes me hurt, sad, frustrated, disheartened, MAD AF and the list goes on... I really hope they will work on creating a better device with more options in the future... that also functions correctly :'( ... show more

  • Worth the money?
Size: 30 Count (Pack of 1) Style: 30 Fertility Tests
I have a love-hate relationship with the Clearblue Fertility Monitor. Firstly, I do not have any known fertility problems and neither does my husband. 4 years ago I bought my first Monitor and was able to conceive my son on the first cycle while only using this method (after 7 months of trying to conceive). Now, my husband and I have been TTC (trying to conceive) for about 5 months (with the monitor, OPK kit, BBT, etc) and have been unsuccessful thus far (although I did have a chemical pregnancy my last cycle). However, I will say that this monitor gives me a LOT of peace of mind. I do not have to guess around like I do with my other methods. It also stores the information from the last 3 cycles and recognizes a "pattern" in your cycles. Yes, the monitor itself is overpriced, BUT if it works, trust me you will not even care about the price once you have your beautiful baby in your arms! We have spent a lot of money already (especially on monitor sticks) trying to conceive our second child. I do recommend this to couples who are trying to conceive..but only after having already tried other cheaper ovulation predictor kits/sticks. If you have a irregular cycle, this may work great for you. If your cycle is like clockwork or you know around when you ovulate, your best bet is to try out regular OPK sticks (for example: clearblue digital ovulation tests) first. If you are prone to miscarriages this would also probably not work well for you, as it does try to recognize a pattern and this may throw it off which would mean you would constantly resetting the monitor and losing your prior information that was stored. Aside from what I have mentioned, the monitor is a great tool for predicting ovulation and increasing your chances of successfully conceiving. I would (and have) definitely recommend this product to other women who are having trouble getting pregnant. ... show more

  • A bit pricey, but best on the market
Size: 30 Count (Pack of 1) Style: 30 Fertility Tests
I have used a one-month supply of these test sticks and they perform well with the Clearblue Easy Fertility Monitor. I have tried a few other kinds of fertility tests and there is no comparison. This is the best. I thought it was a little tough to figure it out the first day or two even though I read the instructions, as I was unsure if I was inserting the stick correctly into the monitor, but now its great. The sticks themselves are individually wrapped and its a little tough to open the protective wrapping. When you open up a stick, the wick is exposed and the lid, which you use to cover the wick when youre done, is on the other end - like a pen cap. Three seconds is all you need, as the instructions state. I am confident that this system is working and that it understands what is happening to my body each day. It is a really powerful tool and it is fantastic. I think it is much too expensive, however. But I would still insist that a person should buy it. Its that good. One side note that I was utterly confused about. The first morning after your period starts is the first day according to the test. I found instructions about that really vague. Also, I accidentally wasted a test stick the first day because I was half asleep and the monitor never asked for a test stick. No harm, but just remember it will tell you when it wants you to test and that wont happen for about 5 days. ... show more
