How did your situation turn out? I am having the same symptoms--I am completely worn out but I normally do not sleep a whole lot, and I can't seem to eat anything--just not hungry. My little guy is 7 months, and I think I need a little more time before another! I just can't quite tell because my periods are still getting back on track as I have recently stopped breastfeeding. I'm just wondering if it turned out that you were pregnant....
Thanks so much!
