My cycle is 31-32 days every month, so once it learned my cycle, it prompted me to test for 10 days straight, usually starting around day 8 or 9. Now my monitor is a good 10 years old but it still works like a champ! Unfortunately for us, even though it would always peg my peak days perfectly, the stars never aligned right and we haven't been able to get preggers naturally.
Good luck everyone!
