I can't stop crying. I cried all day yesterday. Went to bed crying last night and it's started again today. There isn't even a good reason for it. Does anyone have any experience with postpartum depression? The way I have been feeling this pregnancy; I am concerned about where I will be after the baby comes. I have always had "baby blues" postpartum, but nothing I couldn't manage. Should I mention it to my doctor before I deliver?
