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! 🤍

GAME CHANGER!!
SO much better than the average 2 line ovulation tests. I’ve been TTC for a year and a half, and these are the best ovulation tests I’ve used so far (and I’ve used a lot, lol) Digital read is so clear - never questioning if the lines “darkest” or not, because it tells you! & the app keeps track of it all for you!!!

The device froze and I can’t use it. I only used one test out of the 16
I’m updating my results to 4 stars.

Does what it says!
I have really enjoyed using these ovulation sticks. It’s my first time with them. I have 7 kids and was ready to conceive again. Being that I’m 38, I didn’t want to waste time. I’ve used this along with the premom sticks as well as observing my CM. I definitely got to the empty circle for a few days before I started getting the flashing smiley face and lastly, the steady one. It is easy to use and it helps in confirming what the OPK & CM are saying. I also got a second box (for the sticks) but I was still able to use the first test reader FYI. Overall, very pleased with it!

Got my baby after months of trying. This is a God-send.
Follow this to the T and you will get a positive result, that and removing all infertile suits such as "seedless" anything and you will get your pregnant positive results. This was a god send. Thank you, Clearblue.

12 High Fertile days with no Ovulation
My husband and I began trying to conceive last month. As I turned 34 in September, I wanted to become pregnant ASAP. With our first child, I just stopped birth control and didn't worry about timing. I got pregnant the first month. That was 5 years ago and I was worried that it wouldn't be so easy this time. Now, I will admit that I did not follow the instructions to the letter. I was worried about missing my fertile window, so I began testing on the last day of my period, which is a few days earlier than they suggest in the directions. I got negatives for the first 3-4 days, then I started getting flashing smileys. We had sex on a Tues, then Thurs(days 7 and 9),and skipped a few days because we were tired and not getting along. I continued to get flashing smileys into the next week. We had sex on Mon night(actually early Tues A.M., day 13/14). I think I ovulated on Wed, still getting the flashing smileys. I started feeling pregnancy symptoms on Thurs (day16). All told, I had 12 "high fertile" days. It never pinpointed ovulation. Luckily, I was keeping track of my days with an app on my phone. I continued to feel symptoms for 2 weeks after. My period was due today, so I took 3 tests: 2 were (+) and 1 was (-). I still was able to get pregnant but I can't say this test helped very much. I will say that if I hadn't turned out to be pregnant, I was going to give this test another try. It is easy to use and read. It's much better than those generic tests where you have to determine how light/dark the lines are. Update: I miscarried in December and we started trying to conceive again at the beginning of February. I was using these tests again, along with another brand of OPK (Easy@Home). The first month, I never got a clear positive result from either test and, again, had many High Fertile (flashing smileys) on the Clear Blue. I followed the directions exactly this time around. I then started testing in the afternoon/evening because I read that the first morning urine is not really the best for detecting the ovulation surge. I was getting the same thing: a two or three days of Negatives followed by many days of High Fertile on the Clear Blue. I decided to start taking my basal body temperature every morning and switched to a less expensive brand of OPK in order to determine if I actually was ovulating and when. I saved a few Clear Blue and Easy@Home tests to compare if I ever did get a positive result with the new brand. I got a positive yesterday evening but forgot to save my urine. I decided to go ahead and test again, this morning, and used all three tests. All three were positve! It's only day 6 of my cycle, so it's pretty early to be ovulating and if I am an early ovulator then maybe I just missed it before (but I am pretty sure I tested this early in the past) or maybe I wasn't ovulating at all during those months. It's also possible that my hormones were still out of whack from the miscarriage. I have changed my original rating from 3 to 4 stars. Since these tests are more expensive and I am becoming more comfortable with the other test strips, I may not be purchasing these in the future. I haven't decided yet and I'm hoping I won't need to test anymore. Update: I did become pregnant from that cycle.

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.
