Advanced Clearblue Ovulation

Hi - thanks so much for contacting us!  This test is different from other ovulation tests in that it tracks the changes in 2 hormones throughout the menstrual cycle:  estrogen and LH.  If the necessary changes in estrogen are detected, the holder will show High Fertility (flashing smiley).  And if an LH surge is detected, the holder will show Peak Fertility (solid smiley).  It’s possible for the holder to change from Low to Peak without displaying High Fertility.  This can happen if your estrogen level isn’t high enough to be detected by the test, if your hormone changes occur on the same day, if a test is inadvertently missed, or if testing begins too late in your cycle.  You can be assured that you’ve still found your two best days to conceive.

Hope this helps!
