How to get pregnant ?

You can only get pregnant if you have unprotected sex during the few days each menstrual cycle leading up to and including the day of ovulation. So, if you are trying to conceive Clearblue Ovulation Tests enable you to identify these fertile days helping you to get pregnant faster. 


Am I pregnant ?

Various early pregnancy symptoms can indicate you might be pregnant. They differ from woman to woman and from pregnancy to pregnancy. If you are pregnant, you may notice one or more of these symptoms or none at all. That’s why Clearblue® Early Detection Pregnancy Test can be used up to 6 days before your missed period, which is 5 days before the day you would expect your period to start (your ‘expected period’ day).4
