Where did my symptoms go?

Brittany
I'm 5 weeks exactly and literally over night my symptoms seemed to have disappeared. Cramping? Gone. Nausea? Gone. Fatigue? Gone. Sore breasts? Mostly gone. No spotting/bleeding whatsoever. 
This is normal correct? As a first time mom, I'm not sure what to expect. So the fact that in less than 24 hours my symptoms pretty much went away, it's making me a little nervous.
