Clear Blue Digital - when to test?

Hi ladies! I'm planning to start opk testing with Easy@Home starting CD12. Once I see it go darker, I'll start using the Clear Blue Advanced Digi. Two questions on this... First, it says to test FMU, but I'm afraid that it won't pick up LH surge if it's in the afternoon. Should I plan to test FMU and then again in the afternoon once I get the flashing smiley, or stick to the directions and only test FMU? Also, I have my tester and extra strips left over from last cycle. Should I replace the tester with a new one since it's programmed with my last cycle, or do I reuse? I'll have to get another one anyway since I don't have enough strips, but just curious if you need a new tester every cycle?

Thanks ladies!

bump, anyone?

It's calibrated for FMU so use FMU with that one.

I am 99% sure you need a new tester each cycle and you'll have to start earlier than CD 12 because that is how they work.

Since I answer posts from oldest to newest, you should give me a day or two or more like 5 LOL before bumping, it just makes your post go back to the newest and makes me take that much longer to reply. :)
