Pregnancy Symptoms

I found out I was pregnant at 4 weeks and 2days. I will be 9 weeks on Wednesday. The first few weeks I had really sore boobs and was extremely tired. I was nauseous for about 3 days straight but never threw up. My boobs aren't very sore anymore but I am still tired all the time. I have had little cramping but it feels more like pinching than anything. Am I the only one with no symptoms? I feel like there is something wrong!!
