I test with FMU and a second time after work around 4:30pm. The line has to be as dark or darker then the control line in order to be positive.

@BalticBee:  I usually test with early afternoon.  I am one of those people who always get a faint line no matter where I am in my cycle so often if I use FMU I get a darker reading for no reason.

As @RoyalLime: said, test line should be as dark or darker 🙂

@BalticBee:  yep, just as long as it is AS dark or darker you’re good to go. i tend to test at around 5.30pm when i get home from work. ive noticed that i can still get a positive the day after ovulation with FMU, when my temp is already up and it’s probably too late, so i prefer afternoon.
