Holy crap, when does menopause come?

Oh my God, I was so freaking warm last night, and this morning, I woke up and turned the fan in the living room on high just to try to cool off a little. I wound up strapping Baby into his toddler chair and hitting a cold shower. Yikes, this can't be menopause, can it? I am WAY too young for that, right? Time to visit the University of Google...
