Ok this is probably a really stupid question but why do you have to temp in the morning? Wouldn't your temp be raised even at night, so for example if you are usually 36.1 at night wouldn't it be 36.9 if you are ovulating? wouldn't your average temp go up accross the board?

I only ask because I temp at night and in the morning and the temps are pretty steady and I have a REALLY bad tendency to forget first thing in the morning when I'm all sleepy and cranky pants....
