Today has been hell. I'm usually on the go and feel great. Today my head hurts, my upper back is so sore and I'm sluggish. All I want to do is sleep(which I can't do at night or day but today I was able to nap, weird!). I haven't been like this since early pregnancy. It's like I'm sick but I'm not really sick if you get that. Anyone else have this onset later in pregnancy? This blows!
