Identify your 2 most fertile days

Pinpointing Your LH Surge

In every cycle there are only a few days when a woman can conceive, so having sex on these days is very important if you are trying to get pregnant. Did you know that 1 in 2 couples could be trying to conceive on the wrong days of the woman's cycle?² And did you know that your basal body temperature only increases after ovulation, making it not much use to aid conception in that cycle? The Clearblue® Digital Ovulation Test detects the rise of the ovulation hormone LH (luteinizing hormone) 24-36 hours prior to ovulation and identifies the 2 best days to conceive in a given cycle. It's more accurate than calendar and temperature methods³ and gives you unmistakably clear results on a digital display.
