With Charlotte and this pregnancy, no MS at all. Some queasiness from time to time, but def no vomiting etc.

With the twins I was sick from the moment I conceived them! lol So so sick, I couldn't even think of food with out throwing up it was horrible. I was sick right up until the morning I miscarried, even though they had died almost 2 weeks earlier.

Enjoy the sickness-free while you have it, every pregnancy is different and you may not get it at all

WRT to vitamins, as soon as I found out I was pregnant.
