I have had some nausea here and there that started around six weeks but it has been very mild. No vomiting, but heartburn just started. Usually I just get a disgusting overly full feeling in the midafternoon.
Same for me. I'm at 6wks and 4 days and I only just started feeling slightly nauseated, but only randomly...usually when some sort of food is involved, or early mornings (but I think that is also from lack of food through the night). I havent' had any vomiting or heartburn or anything. This is my first pregnancy too (and I'm also over on the July 2013 board!)
