I'm 4 weeks 6 days pregnant with #3 and don't have hardly any symptoms?

My bbs are a little sore and it flucuates from day to day, my lower back hurts a little and that's about it. I've had a bad cold/congestion for about 5 days. That started just a few days after I found out. I'm searching my mind to remember what I felt this early with my 2nd baby but that was almost 9 years ago so I don't remember very much, plus I had a 12 month old at the time so my focus was on him. Anyways, I think by now I as nauseated and dizzy and smells bothered me a lot. I know I should consider myself lucky but I just feel like I should be feeling more pregnant than I am. Anyone else have little or no symptoms at almost 5 weeks?
