Clearblue Digital Ovulation Test is a comprehensive fertility monitoring system that includes 10 test sticks. This digital test identifies your 2 most fertile days by detecting the surge in luteinizing hormone (LH) that triggers ovulation, helping you maximize your chances of getting pregnant naturally. The test provides clear digital results with a smiley face indicating peak fertility days. For best results, testing should begin according to your cycle length. The digital reader interprets your hormone levels and clearly displays results on the screen. As this is a personal medical diagnostic device, please carefully read all instructions before use and consult with a healthcare provider about proper timing of testing based on your individual cycle.
