The Clearblue Ovulation Test and Clearblue Digital Ovulation Test detect the luteinising hormone (LH) surge which occurs approximately 24-36 hours prior to ovulation. This is how they help you pinpoint the 2 best days of your cycle to get pregnant - the day before ovulation and the day of ovulation itself. So, if you have intercourse on these 2 days, you’ll be giving yourself the best chance of becoming pregnant.
The Clearblue Digital Ovulation Test with Dual Hormone Indicator is a breakthrough innovation in ovulation tests. Not only does it detect the rise in LH, it also detects the rise in another key fertility hormone, estrogen, which increases in the days before the LH surge. Because your partner’s sperm can survive in your body for up to 5 days, you can actually become pregnant by having intercourse in the days leading up to ovulation. By tracking these 2 key hormones, this Clearblue test is able to typically identify 4 fertile days leading up to, and including the day of ovulation, twice as many as other tests.
The Clearblue Fertility Monitor is proven to increase the chance of getting pregnant by 89%.1 It is the most advanced home method, typically identifying 6 fertile days each cycle. It not only detects the LH surge and pinpoints your 2 Peak Fertility days, but also identifies additional High Fertility days when you may get pregnant, by detecting the rise in estrogen which occurs before the LH surge. As your partner’s sperm can survive in your body for several days, having intercourse on both High and Peak Fertility days maximises your chance of getting pregnant. Because the Clearblue Fertility Monitor stores information from your tests, it learns about your fertility pattern, giving you personal information about your daily fertility status. It even tells you when to test and also when your period is due which helps you work out when you can test to see if you are pregnant.
