Trying for a baby? Clearblue Advanced Digital Ovulation kit is proven to double your chances of getting pregnant (1). Accurately pinpoints your 2 most fertile days each cycle, so you can maximise your chances of getting pregnant naturally. By accurately tracking 2 key fertility hormones, estrogen and luteinising hormone, this ovulation test not only identifies 2 peak fertility days, but also additional high fertility days before that. This means you have more opportunities to get pregnant - at least twice as many as with any other ovulation test (1). Unlike basal body temperature (BBT) charting, ovulation predictor kits detect the rise in luteinisning hormone (LH) that rises prior to ovulation to accurately detect the days before, and not after ovulation. Unlike other ovulation tests which track LH only, Clearblue Advanced also detects estrogen which rises prior to the LH surge to detect more fertile days. Because your partner’s sperm can survive in your body for up to 5 days, you can actually become pregnant by having intercourse during the days leading up to ovulation. Have intercourse on high and peak fertility days to maximise your chances of getting pregnant. The clear digital display gives you a Clearblue smiley face when it identifies your best days to get pregnant so you know your body is ready. Clearblue Advanced Digital tested over 99% accurate at detecting the LH surge.(1) In first cycle of use, vs not using ovulation test.(2) In a study of 87 women, 4 or more fertile days were identified in 80% of cycles using actual cycle length (2012).Accurately pinpoints your 2 most fertile days each cycle, so you can maximise your chances of getting pregnant naturally.
