I don't know, it could change it by a bit. There's a website I sometimes use to adjust my temp if I have to take it early -- https://www.whenmybaby.com/basalbodytemperature.php
I can't guarantee that it's accurate, but I've tried once or twice taking my temp at the usual time, then going back to sleep and taking it again and seeing how the adjusted late temp compares to the normal one, and it seems pretty good. FF doesn't recommend adjusting, but you can try it both ways and see (I always put a note in the box to say whether I adjusted or not and how much).
