How soon can your body show preg symptoms?

I was only a few days when I found out I was preg with my daughter,***** test at hospital cuz I was throwing up. I was only at 22hgc. If I am preg I'm anwhere from 2 weeks to 2 days shy a week. I'm feeling nauseas and more hungry then usual....not incredibley but enough where the fiance has noticed lol. I've become a lil more tired then usual, and sometime my uterus feels a lil more "sensative". I'm not 100% what symptoms I should be showing,could be showing and so on. With my daughter I was only tired and sometimes really hugry but they say each pregnancy is different. Someone shine a little light on the subject for me please and thank you.
