I had mine from 7 weeks to about 17 weeks.
It started off as nausea and just feeling like I was hungover (badly!) all day. It was especially worse in the mornings and the evenings.
About half-way thru it changed to more "classic" m/s.
I'd get up in the morning, drink a big glass of juice then wait an hour or so and throw the entire thing up. I was then fine for the rest of the day (just a little queasy sometimes). I much preferred that type of m/s because at least I knew I'd be ok once I threw up.
One warning tho... if you have that type of m/s... don't have spaghetti bol for breakfast.... ewwwwwwww! That was a bad morning!
