Night Shifters!

I'm a nurse and work 7pm-7am. I have trouble with checking my bbt bc on my days off I flip back to a daytime schedule, so my waking up time varies greatly depending on the day. Any fellow night shifters have any tips for bbt? Switching to days is not an option at this time and won't be for several months.
