Clearblue Advanced Digital Ovulation Test typically identifies your four best days to get pregnant naturally. By accurately tracking two key fertility hormones, estrogen and luteinising hormone (LH), it identifies two peak fertility days, like all other ovulation tests, but also typically two high fertility days before that, so you have more opportunities to get pregnant. Its unique, smart algorithm adapts every time you test to indicate your personal wider fertility window. Have intercourse on High and Peak fertility days to maximise your chances of getting pregnant naturally. The unmistakably clear Clearblue Digital smiley face will tell you when your body is ready. Clearblue Digital tested over 99% accurate at detecting the LH surge in laboratory trials.
The day you need to start testing depends on your cycle length and the instruction leaflet provided will help you work this out.
If the test shows Low Fertility, you are unlikely to fall pregnant if you have sex today. Test again tomorrow.
If the test shows High Fertility, you can increase your chance of getting pregnant by having sex today but you should test again tomorrow.
When the first Peak Fertility is shown, ovulation should occur within the next 24-36 hours. The next two days are when you are at your most fertile and having sex will maximise your chance of getting pregnant.
