No, it is normal to have cravings and morning sickness...it is also normal to not have either. People have different symptoms during pregnancy. You sound like you are going to have an easy one. Or you could get morning sickness and cravings later in your pregnancy also. Don't get worried about this being signs of miscarriage...cause its not.
With my first I never had morning sickness. With this one it was bad til about this wk. 9wks
Not just based on no morning sickness. There maybe other factors that could cause you to miscarry but the lack of morning sickness isn't a sign that you are. I'm pregnant with number four and I've never had morning sickness in any of my pregnancies. :-)
