BACKED BY SCIENCE: The NC algorithm uses basal body temperature to identify fertile and non-fertile days and to confirm ovulation. Taking ovulation tests is optional and can help the NC algorithm predict your ovulation day
IDENTIFY THE MOST FERTILE DAYS: Use Clearblue Digital Ovulation Tests to identify the surge in luteinizing hormone (LH). This happens 24-36 hours before ovulation to identify your 2 most fertile days
CLEAR RESULTS: a flat line indicates No LH surge (‘Negative’) and a line with a surge indicates an LH surge (‘Positive’)
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')
