Is it normal to have no symptoms?

My due date is December 10, so I'm 5 weeks 5 days along. I found out I'm pregnant on Sunday! My husband and I have been TTC, we are so excited! But I'm feeling really good...I don't have symptoms at all. Few days ago I had minor cramping, and last night my boobs hurt a little bit but not bad; otherwise that's it for symptoms! I don't 'feel' pregnant yet and honestly want some symptoms, as it doesn't seem right to not feel symptoms at all in first trimester! (This is my first pregnancy) Is this normal? Is everything ok or what does this mean? Is it possibly too early?? Any insight would be great and helpful- thank you!
