Clearblue Fertility Monitor & Test Sticks

The Clearblue Advanced Fertility Monitor is the only monitor that detects and stores fertility and pregnancy information. It accurately measures the levels of the 2 essential fertility hormones (estrogen and luteinizing hormone) and determines your fertility window in each cycle, within which your chances of conception are greatest (the few days before and during ovulation) and then you can do a pregnancy test right away to check your success.
