Normal?

Ashley
So, I've read a lot of posts about women having all kinds of symptoms. This will be my first and I'm 6weeks, but sometimes forget I'm pregnant. I mean I have nausea if I don't eat every couple of hours or if I eat to much and my beasts are incredible sore but I haven't had any morning sickness. I may wake up a bit nauseous because I haven't eaten anything all night but as soon as I start to snack I'm fine. I've trying to eat healthy but certain things do make me nauseous just at the thought, like chicken.... ugh. But is this normal, to not have morning sickness yet? My sister, who's also pregnant, has had a horrible time with morning sickness and my mom said she suffered with it for almost the whole 9 months. Should I just knock on wood and count my blessings or worry that things aren't progressing like they should be?
