No early symptoms but still pregnant?

Katy • TTC #1!! Just married in September and focusing on stress reduction and healthy living habits
I'm 11DPO and have had no change in symptoms. I'm exhausted but I just started a new job and I know that's what it is. Just wondering if anyone who is pregnant had no symptoms until much later. I've been BFN so far and I'm basically thinking I'm out because it just doesn't feel like I'm pregnant. Anyone have the same situation?
