When to start testing for ovulation?

How to determine which day to start testing

If you would like to use a Clearblue® Ovulation Test and are wondering when you should start testing, this tool can help you. 

If you don’t know your cycle length, we suggest you wait for your next cycle and note the day your period starts (Day 1) and the length of this cycle before using this online Ovulation Calculator tool*.

E.g., 22/02/2024
If you don't know your cycle length, we suggest you wait for your next cycle and note the day your period starts (Day 1) and the length of this cycle before using this online tool*.
To measure the length of your menstrual cycle, count from the day your period starts to the day before your next period starts.
 

If you don't know your menstrual cycle length, wait until you've had at least one cycle, then come back to use this calculator. If your cycle length varies by more than three days, choose the shortest cycle you've had in the last six months to work out when to start testing.

Advanced Digital Ovulation Test

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. The Clearblue® Advanced Digital Ovulation Test is the first and ONLY test that typically identifies 4 or more fertile days each cycle.
