Hey Meg..
Put down that thermometer, Momma! I did the same with DD #2 and I almost drove myself batty. Your temp can fluctuate wildly when you are actually pregnant (finally! WOOT!) and all it will do is make you worry too much. And we don't want too much worry when little one is trying to stick.
Just throw it away. Take it with you to the store and throw it in a trash can where you cannot fish it out in the morning!

That is what I did, on the advice of my co-workers (maternity nurses, lol!) and I felt much better.
DD proved to me that she was sticking by making me puke 24 hours a day. I've never been so happy to be sick to my stomach
Best wishes for a fabulous pregnancy!
