Backed by a science-driven algorithm that integrates basal body temperature and test results, it offers clear digital readings to empower natural fertility tracking and birth control decisions. ## Description 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'). Review: 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!
