I am now 38 weeks pregnant. Countdown to baby has begun. Lately at night I have started to feel strange. I almost feel slightly nauseous. I just feel sort of sick but not to the point that I think I am really getting sick. I am not sure how else to describe the feeling. This doesn't happen every night but it does happen most nights. I usually just go to bed because I don't feel like doing anything else. Does anyone have any idea why I feel so strange or almost sick at night?
