ugggg I feel for you. I don't know how you can do it. is it a desk job or lots of walking? with my first pregnantcy I was super woman. I felt like I could do it all. I was very active most if the time. I worked up till my last week of pregnancy. mainly cause my boss said I had to. this pregnancy, no. if I worked retail still, I would have quit. I work from home and thank goodness. it may hurt sitting at a desk all day. but I'm more relaxed with it, and I'm not hurting myself.
:( awww. hopefully today will go by fast so you can get home and go to bed. use your lunch break for sleep.
