when do symptoms hit?

Rachel
I am only 5 weeks along so I know it's very early, but the only symptoms I have are being exhausted and hungry. My boobs aren't sore, I'm not nauseous, and no food aversions. Is this normal? I'm not sure if it's because it's so early in my pregnancy or if something's wrong. Since this is my first pregnancy, I am not sure what to expect!!
