I'm Exhausted

Last night I went to bed with plans to get up early and clean the house so tomorrow I can just relax. I got up walked the dogs and started to clean. I received a phone call from my Aunt and decided to take a break and make the journey down to my grandparents with her. I figured I would just pick up where I left off when I got home. I got home about an hour ago. Do you think I've switched around the laundry, unloaded the dishwasher, swept the floor, or even picked up a cleaning rag? NO!!! Needless to say folks, I'M EXHAUSTED! Seriously, I didn't even do anything today. My normal day consists of standing on my feet for 8 hours, lifting boxes, the normal retail routine. Today I've done squat, nada, nothing. My husband is going to come home and wonder what I did all day. I guess everyone is entitled to a lazy day, right? When I posted on facebook that I was exhausted.... I received the comment of, "That's a sign of pregnancy". I already knew that but I would only be like a week pregnant. Is it possible to have signs this early? You see, usually I'm comparing every single symptom I have to see if I show signs of pregnancy. Let's just say I always get my hopes up and then I get crushed. So this month I decided I'm just going to act like it's a regular month. I'm not going to compare symptoms, I'm not even going to test early. I'm just going to wait for AF and hope I don't get it. Needless to say, this is going to be a long week.
