I am 6 weeks pregnant with my first and what started out last week as mild nausea now seems to be worse each day and lasts pretty much the whole day unless I eat constantly! No actually barfing yet, thankfully, and I'm probably just being a wuss, but am beginning to panic about going back to my teaching job at the beginning of Sept if I still feel this off-colour all day. Anyone have any useful experiences, or just funny ones that will make me laugh!?!
