How it works

To use the Clearblue & Natural Cycles Birth Control Ovulation Test Refill Pack, remove the test strip from the foil, insert into the holder, wait for the ready signal, and either urinate directly on the test strip, or use a cup to collect your sample and soak the test strip. The holder will start to blink to let you know it is analyzing the sample. Within three minutes, you will see your result on the digital screen. Using ovulation tests alongside Natural Cycles can lead to up to 5% more green days per cycle.

Please read through the included instruction booklet before using.
