How are the advance test sticks different than the older ones?
I own a Clear Blue Easy Fertility Monitor. I have own this for 5 years and use it to confirm ovulation. The usual places that used to carry the test sticks seem to not carry them anymore. I am reading on line about the "Clearblue Advanced Fertility Monitor Fertility Test Sticks", would this work with my monitor? - How are they diff from what I was previously using?
