Every pregnancy is unique so just look after yourself and your body will look after baby.
First off congrats!!! And yes that sounds perfectly normal, though I had crazy morning sickness which is how I knew I was pregnant. But there's not too many changes that early on other than fatigue and be happy you have an increased appetite not a decreased! :)
The only symptoms I have ever had were sore boobs and being tired and maybe some headaches. Many women don't have morning sickness. Just consider your self lucky and make sure you get check out by on OB. Don't worry! Everyone is different and some people feel idderent symptoms then others.
