BBT and OPK timing.

Summer • Had a TR Jan 4th 2016, TTC #1 in my new marriage.
I just started taking my temp today and was told that I'm gonna be moved to swing shift which is 3 to 11 instead of regular day shift 7-3. How do I switch up the timing without throwing everything off. I was taking it at 5:15 every morning. I'm also gonna start taking ovulation tests and was planning on doing that around 4 in the afternoon. Will sleeping schedules change my tests timing also?
