5.5 weeks. don't feel pregnant?

I'm 5 weeks and 5 days pregnant but I don't really have any symptoms. My boobs were really sore before but seem to letting up. Same with fatigue. Is this normal? Anyone else? My first doctors appointment isn't until May 25. This is my second pregnancy. I had my first child 7 years ago and honestly don't remember what symptoms I did and when... I'm trying not to worry but I can't help it!
