Nausea and vomiting disappearing at 8 weeks 6 days .

Chasity

Since I was 5 weeks give or take I had the worst nausea and vomiting all day , but now at almost 9 weeks they are starting to fade . Yesterday I had my 8 week sono and the baby is doing great so far , measuring a day ahead even . Should I be worried that something may be wrong in a few weeks or is this normal ? Certain food smells and the thought of certain foods still turn me off .
