Exhausted

Cara • Expecting our first baby Jan 1st 2016! Married my best friend after 8 years together 10/10/14.
Does the exhaustion ever let up? Lol! I am only 6 weeks and I teach kindergarten. Every day when I come home around 4:30 I lay in bed and have a hard time getting back up! I'm just so physically exhausted! It feels so good to lay down and do nothing. I feel like I could sleep for a month and still be tired! :-(
