I was never really sick during either pregnancy. First time (not nursing, obviously) I was horrendously fatigued for the first month or so and if I leapt out of bed in the morning, might feel slightly nauseated for a few minutes. Second pregnancy (nursed all through it) I didn't even get the fatigue, but felt vaguely nauseated once in awhile. Had no nipple tenderness either, which surprised me.
