Trouble sleeping?

Brittney
I swear the last 3 days in a row I've woken up drenched in sweat and I can't sleep through the night if my life depended on it. It's been in the 40's and 50's at night and we sleep with our window wide open with the fan blowing the cool air right at us but I still sweat like crazy. Any one else having this same issue? Or have any advice? I'm 6w4d with our first.
