Morning sickness all of a sudden?

I've been mildly nauseous with a few dry heaves until now. All of a sudden at 9 weeks I've been actually vomiting, especially when I smell something bad. My first appointment with the midwife is tomorrow, just curious if any women all of a sudden started feeling sick. With my first I didn't really have morning sickness at all. Twins run in my family so I haven't ruled those out yet.
