Best of luck to you, Lisa Marie! I've not been pregnant yet myself, but have watched a few friends go through it, and they were all really really dragging the last month or two. I firmly believe that we should always listen to the messages our body gives us, and your body is probably telling you to rest to prep for labor and having a newborn! So listen!
Are you still working? Will you go back to work afterward? How soon will you go back to work after your daughter is born?
