Newbie to bbt

I’ll be starting to temp this cycle and I was looking for advise? I wake up a few times throughout the night, never for long, but I do wake up as I toss and turn. Will that affect my temps? My husband wakes up at 4 for work and usually wakes me, but I fall back to sleep until my alarm wakes me at 5:20. Should I temp at 4 when he first wakes me?

Thank you in advance!
