Morning sickness yet?

Madelaine
I'm exactly 6 weeks today and other than a few food aversions and a tiny bit of nausea if I get too hungry, I've not had any morning sickness. Honestly, my appetite is almost more than before I got pregnant. What is the typical week I can expect MS to rear its ugly head? Any of you ladies already in the throes of MS? Or any of y'all not experiencing this yet? I had two friends who escaped their pregnancies without it, so maybe I'm the same? I've just heard that pregnancy symptoms, like MS are a sign of a normal, healthy pregnancy and it's worrying me that I've not had the typical symptoms yet!
