Morning sickness this early?Possible???

m 9dpo. & 3-4 days from expected period. And last 2 days I've been having bouts of nausea. ESP if I wait too long to eat. No vomiting yet, knock on wood. Is that too soon for it to be morning sickness? My First preg. No sickness, no symptoms ever. 2nd pregnancy with twins I had all day all night severe sickness from about day 1 til delivery day. I just don't remember when "day 1" was. Kids are 12, 9 & 9. So I really don't remember when I started to feel yucky. IF you had nausea, when did it start? Do you think 9dpo is too soon for nausea? Thanks everyone!!
