Would this affect basal body temp

I purchased a new Apple Watch in April and have been using it to take my temp at night to track ovulation to help get pregnant. If I understand correctly the watch frequently takes my temp during the sleep time I have set of 11:00pm-6:30am. My question is, if I get a bad nights sleep where I’m awake for a good chunk of time (like hours) will my basal body temp be accurate?
