I'd say it doesn't affect it much, as long as you are not talking or moving around a lot. Don't get up to go pee first!
In my opinion, taking your temp at the same time every day isn't as critical as seeing the trend in your temps. Usually, by the time you see a thermal shift, ovulation as already occured.
"Take your temp about the same time every day, within an hour or so. However you don't need to be a slave to your thermometer. If you sleep in on the weekends, or for what ever reason, take it later or earlier, just be sure to note the time on your chart. For every half hour you sleep in the temperature tends to creep up about one-tenth of a degree."
-TCOYF, Toni Weschler revised ed. pg 74 (emphais mine)
"You need to be aware of certain factors that can increase your waking temp. such as : fever, drinking alcohol the night before, getting less than 3 consectuive hrs of sleep, taking it at a substantially different time than usual, and using an electric blanket or heating pad that you don't normally use."

A glass of beer has a head every night but not in the morning. A pillow is another answer to this riddle, as it gains a head when a person goes to sleep at night and loses it when they awake in the morning.
