This works as promised, but MUST read instructions!
I bought this test only after doing much research online and looking at reviews here and on other sites. The negative reviews really almost swayed me into not trying this product; but, I researched more and then closely looked at exactly what the negative reviews were complaining about. So, I bought it, used it, loved it, waiting to see if this month is my BFP. Here's a rundown of this ovulation kit and here's hoping that I can answer some of the questions and concerns that others might have that are considering this product. This information is also available on the website, and in the instructions. This kit is designed to test over a number of days. In this way, it will catch the rise in estrogen levels that precede the LH surge (ovulation). A blank circle is low fertility. A flashing smiley face is high fertility. This means that the meter is showing a rise in estrogen levels in your urine. Most women will have 2 days of flashing smiley faces before the peak fertility is reached. Peak fertility is a smiley face. Once peak is reached, the meter shows the result for 48 hours, which is a reminder to you that your best chance to conceive is the next 48 hours. Now, a lot of confusion seems to center around the flashing smiley. Generally, most women will see this for 2 days before peak fertility. That's a general statement. Each of us is different and unique and your result may be different. If you get a flashing smiley face for more that 9 days, then there are a couple of things to consider. One: did you start testing too early? If you test too early, estrogen is the leader of the pack for the time around your period and testing too early will pick up that higher estrogen level. There is a clear chart of when to test. It will also line up with any ovulation/fertility app or fertility prediction chart. Testing too early won't give you a headstart, it'll give you a headache. If you find that you are testing during that time frame and NOT seeing LH surges, then you would want to talk to your doctor. Two: we don't always ovulate every cycle! I know that's the last thing we want to hear when we are peeing on a stick, taking temps, performing midnight fertility dances under the full moon and so on; but, it's true. Third: sometimes the LH surge is so small that the meter can't pick it up. Sometimes the meter will go from LOW to PEAK from one day to the next. This typically means that you started testing too late for the meter to catch the high fertility days and it only caught the LH surge. Next cycle, start at the recommended cycle day to begin testing and this should give you the low-high-peak progression that you are looking for. Once that static smiley face is reached, your LH surge has been detected and you are at your highest chance of conception. The meter will show that smiley face for 48 hours as a reminder to you that you are at peak fertility. Once the smiley face goes away, the fertile window has closed. You CAN'T test with the meter after peak fertility is detected. Well, you can think that you are. You can throw a test strip in there, not look to see the symbol that says "ready to test" and proceed to test tap water, dr pepper, sam adams, kool aid or whatever you feel like testing and the meter will still show peak fertility because it ISN'T ACTUALLY TESTING. If you want to test again after peak fertility has gone (that means the display is blank and you get the new cycle symbol and the ready to test symbol when you insert the stick) then, and only then, can you test again. I don't know why you would need to test again, but if you absolutely feel the need to, you could. But, chances are, your ovulation is long past. I saw a couple of posts where this test kit was compared to wondfo or other test strips. Those test strips can be pretty tricky to read. Just because you have two lines there, that doesn't mean you have an LH surge. For those types of tests, the test line must be as dark as or darker than the control line. If you prefer to use a lot of sticks, those would be your best economical strips to use. I would recommend that you place them in a notebook or on a notepad with the cycle day and time of test, glued in place, and watch the progression. That will show you how best to look for the dark line that tells you that your LH surge is on its way. But, those strips can make you want to tear out your hair if you don't do that, because it's really hard to catch the pattern if you don't save the strips. I used those for several months. They are messy and difficult to read. The clearblue test is easy and mess-free. I also hear (read) a lot of complaints about the price, and this one confuses me. Yes, it's about $40, but it should last 1-2 cycles (it might make me 3) and this cost is far less than the cost of an infant when you figure in medical costs, clothing, diapers, etc. It's a good test. It really works. I got 2 days of low, 2 days of high and then peak. I highly recommend it. But, read ALL the instructions and begin testing on the day that they recommend, or you might find yourself frustrated and confused. It is different that most of the other OPK out there, and I wonder if that causes a lot of the confusion.

Game Changer for Tracking Your Cycle!
I've tried a few different ovulation tests over the past several months, and the Clearblue Advanced Digital Ovulation Test is hands down the best one I've used. What sets it apart is that it doesn't just tell you when you're at peak fertility — it also detects your high fertility days leading up to it, so you get a fuller picture of your window. No more squinting at lines trying to guess if it's "dark enough"! The smiley face display makes reading results so simple and stress-free. When I got that solid smiley, there was zero confusion — just clarity and excitement. The process of tracking can already feel overwhelming, so having a test that's this straightforward is genuinely a relief. The tests are easy to use, the instructions are clear, and the results come quickly. Honestly, I feel so much more informed about my cycle now than I ever did before. Worth every penny. Highly recommend to anyone on their TTC journey! 🤍

Most Definitely Works!
Definitely helped me know when I was ovulating, high fertility and peak fertility! I didn’t need another kit because I got pregnant before I could buy another one lol so this definitely does help!!!

Use if trying ton conceive!
Love this product. This helps to determine if I was ovulating. I used this the last time when I conceived my daughter and it only took 1 month.

Still a great product
We used the original Clear Blue digital ovulation test (pink model) a few years ago when we had our son. I gave this advanced model a shot this month as we’re working on baby #2. The only difference in the device thus far (aside from the App tracker and the extra pregnancy tests) is that the cartridge docks into the handle more securely. That’s not to say that the original isn’t amazing, it is, but the original would have a few cartridges fail a month as they wouldn’t click in completely. I’ve only used the purple advanced version 5 times, but so far, no wasted cartridges. Only downside is that the test takes a bit longer to run. Make yourself comfy as it takes 5-7 mins until you see the indicator.

Can't actually see estrogen/LH levels; no way to track, view, or share data.
Reliable but Weirdly Vague and Dishonest About It's "Advanced" and Detailed Results (Best as a Backup to More Detailed Apps) I’ve been using the Clearblue Advanced Digital Ovulation Test with its companion phone app, and my feelings are very mixed. It's almost funny how silly it is that this testing kit can do so much yet show us so little. On the plus side, the product is aesthetically pleasing, very user‑friendly, and the app interface is clean and uncluttered. Clearblue also has strong brand recognition and a reputation for reliability, and I *do* feel I can trust the results it gives me. Another big selling point is that it tests for two fertility hormones (LH and estrogen) instead of just LH, which is why I chose it over brands like Easy@Home and PreMom. BUT! The problem is, you won't ever see that "data." The way Clearblue presents those results is, in my opinion, the main flaw. Even though it’s detecting more hormones, the only feedback you actually see is: - Low fertility – empty circle - High fertility – flashing smiley - Peak fertility – solid smiley That’s it. You don’t see any hormone levels, don't see the estrogen or LH levels it tracks, don't see surges, spikes, trends, or numbers. Just flashing symbols you enter into a calendar that then tells you when you should sleep together to procreate. I spent a long time going through the instructions and tutorials because I assumed I HAD to be missing something! When I finally asked the in‑app chatbot, it compared it to a GPS: "it tells you to when to “turn left” without explaining why or what’s going on behind the scenes." That’s exactly how it feels – you’re told what to do, but you’re not allowed to understand why or what’s happening with your own body. I also assumed that once I downloaded the app, I’d be able to sync more detailed info/data to my phone and see what was happening with my hormones over time. Instead, the app mainly has you log the icons you see (again: empty circle, flashing smiley, solid smiley) and allows you to log some basic notes and period symptoms. It does not tell you what said symptoms might mean, or let you see actual hormone values or a more nuanced picture of your cycle. Because of that, I think this product is probably best suited to people who are young, generally healthy, and just starting to try for a baby, and/or who don’t feel the need to dig into details like hormone surges vs. peaks, exact LH levels, or long‑term patterns. For basic, simple, early pregnancy planning, it can be helpful: - It can point you toward good days to try to conceive - It can also help you identify lower‑fertility days if you’re trying to avoid pregnancy (though I would still be cautious relying on it as contraception alone) - Clearblue also claims it can identify two more fertile days than standard LH tests with a fixed 25 mIU/mL threshold. That all sounds great, and may very well be true, but the app doesn’t clearly explain how it does this, and again, you don’t see the underlying data. In contrast, I strongly prefer apps like PreMom and Easy@Home for in‑depth fertility tracking. Their apps (both free and paid versions): - Show you actual numbers for LH (and PDG, where applicable) - Let you clearly see surges versus peaks and overall trends - Provide insight and advice based on your patterns - Have an AI chatbot that explains anything you need it to about your results - Allow you to track more symptoms, side effects, and medications than ClearBlue - Give you data you can share with a doctor later if you run into fertility concerns, or just want a more complete record Because of all this, my recommendation is: If you can afford it, use Clearblue as a secondary system, not your only tracker Let Clearblue help confirm and identify additional fertile days Use PreMom, Easy@Home, or a similar/better/fancier (if you can afford it!) detailed app as your primary source of information, insight, and long‑term tracking. **Bottom line:** Clearblue Advanced Digital Ovulation Test Kit may be "advanced" but it's not so clear as to how. It's pros are that it's easy to use, looks nice, and I do trust its results. But cons are it feels oddly and unnecessarily secretive about the extra hormone data it’s collecting, whilst touting how special it is for being able to collect and track it. Even the back of the box shows an "example" chart with a sample LH & Estrogen peak during a cycle - yet I guarantee you will never see any such chart or results when you enter the circle or smiley faces into the app/tracker. You know it’s measuring more, but you never get to see any of it. For me, it makes the most sense as a backup tool alongside a more detailed and transparent app - not as my main way of tracking fertility.

Inconsistent result between digital testers
I bought a new set of this kit since I ran out of the sticks midway. It was blinking lights on the old device before I tested with the new one on the same day, which weirdly shows the empty circle. I tested again today (2 days after my first comparison) with the previous device AND the new device from the newly bought kit, both with the new sticks that comes on my new kit + using same cup of urine for both. It returns to a different result. The previous device was bought from Boots UK while the new one are from Amazon US, so I don’t know if they have different device quality. Considering this set is very expensive I’m really disappointed how it can give me different result. It’s very confusing and sad for me who’s trying to conceive after a devastating ectopic pregnancy loss.
