Clearblue Digital Ovulation Test identifies the surge in luteinizing hormone which happens 24-36 hours before ovulation, to identify your most fertile days. On the days you take a test, add your LH results into the Natural Cycles app (available with Clearblue & Natural Cycles Birth Control Starter Pack). Clearblue Digital Ovulation Test is over 99% accurate at detecting the LH surge. Do not use the LH surge result for contraceptive purposes. The Natural Cycles app uses temperature, period, and (optional) ovulation test data to determine your Green Day (‘Not fertile’) or Red Day (‘Use protection’).

Pricey, but worth it
I got these to go with my natural cycles thermometer and app(10/10 recommend if your are trying to track naturally!) it got here quick, and I think it’s super easy to use. It takes 3 minutes to check to see if your LH has risen. I’ve had a couple funky months with high stress so my cycle has been a little off, but using this to track ovulation has been great. I’ve used it for about 3 months now, off an on based on when the app suggest to check. It’s been pretty accurate. I think that for the money it’s a little pricey, but it does offer ease of mind knowing when you are fertile and when you are not. Battery life is great, and overall great quality!

Strips dont work
Out of 15 only 5 strips worked so far and all other of the strips when inserted read to try another one. PS, the packaging mentioned expiry date of 2026 so it feels I wasted so many strips, time and money. Since, the brand was recommended by Dr. I didnt even feel had options.Due to initial days failure itself , I started tracking with other company strip as well and was able to see, report progress. But this one kept failing every day.Since I had to use to product in hope for next one working and reporting per Dr. Instruction, I cannot even return and I hardly write review so even this feels I am being critical but I hope you make better decision after reading it or the company improves the quality, cz well what is amazon going to do for substandard products?

Good product, needs more options
I’ve never had any issues! Very easy to use— just read the directions and you’ll be fine. Digital reader is so convenient. I use for prevention, but if you want to see LH progression (line darkness over a series of days) just remove the strip from the reader and look at the lines. *My only complaint is the fact that I can’t order the strips only. I got a digital reader in my first box— I don’t need a new one each time. Would be nice to pay a lower price for a box of just the refills and no reader!*

Easy and accurate!
Definitely recommend and is very very accurate. Super easy to use, just like taking a pregnancy test and is a great deal. Way easier to use than the traditional lined strips.

Works ok, but I just go back to regular LH strips
Works ok, but 5 strips did not work. I dont know if it’s user error or the reader failing. I probably will just go back to LH strips again instead of this.

Worth it!
Really love the simplicity paired with the natural cycles app. I have used other ovulation tests but these are worth it if you use natural cycles.
