Late period

Okay... so as of tomorrow I will be a week late. I am usually pretty regular, the last time I was this late was due to extreme stress. I dont feel stressed though, and I was wondering... what kind of early pregnancy symptoms did anyone experience at this early? If any at all? I am really confused and i dont want to talk to anyone I know in person because I don't want them to maybe get their Hope's up for nothing. Any help would be appreciated!!!!
