Clearblue Digital Ovulation Test 10 pieces
It's a self-diagnosis test that helps women trying to conceive determine their most fertile days. It works by detecting changes in ovulation hormone (LH) levels. It has an accuracy of over 99%, and its results are clearly displayed on its digital screen. When the test displays a smiley face, it means it has detected an LH surge, so the chances of pregnancy are higher that day and the next. When the LH surge is not detected, the test displays an empty circle.
