What time to temp with odd sleep schedule?

I’m going to temp for the first time this cycle and I’m looking for advice. I know you’re supposed to take your temperature first thing as soon as you wake up before you get out of bed or even start to move around much. My SO wakes up for work at 3:30 am and that always wakes me up though I don’t get out of bed. I just kind of lay there and pet the dog until he kisses me goodbye and goes to work. Then I fall back to sleep and wake up for work at 6:30.

So, should I test at 3:30 when he wakes up (I’ve usually been asleep about 4 hours by then) or at 6:30 when I get up for work?
