Temp inaccuracies...

I set my alarm to get up for work at 5:30am, some mornings I'm a good girl wake up with the alarm, temp. & get up for the day. Somedays I hit snooze til 5:45am, temp, go back to sleep til 6am & everything in between! Is temping in this 30 min window affecting how accurate my readings are?? I'm not a morning person & I'm finding it very hard to temp @ the same time every morning because I'm half asleep & not wanting to wake up! 😫
