First of all Congratulations!

I didn't get many symptoms a week ago aswell just the tender bb's, light headed and the need to eat all the time.
Then all of a sudden (yesterday) morning sickness started to appear. And I even vomited this morning! Lovely!
So I wouldn't be worried hun, im sure everything is fine and you start feeling nauseas in no time.
I know it's so hard to keep calm about things!
