Exhausted!!!! Anyone else?!?

Stacy.
I am just about 6wks along and I am sooooo tired! I do not remember being this fatigued with my first, at least not this early on. My husband thinks I must be carrying 5 babies to feel this drained ? I have been taking naps when time allows but I almost feel more tired when I wake up and it hasn't seemed to make a difference if it's a quick power nap or I sleep for 2 hours. Thankful to be pregnant but hoping my energy level picks up!
