Charting bbt

Kyra
I don't know if I am able to chart bbt correctly because I get up multiple times during the night to pee. If I chart the temp I take after getting a few hours sleep then it won't be at the same time every day. If I chart the bbt at 5 am every day then I might not have gotten a full 3-5 hours of straight sleep prior to that. Anyone have this happen to them or any advice?
