Am I pregnant?

Breast tenderness, increased discharge, enlarged areolas,dizziness, nausea, vomiting, abdominal cramps, headache, and slightly more than normal shortness of breath. Yet, I'm not due for my period for 12 days. My fertile window should have just ended. I had sex a few days after my period and a couple times since then, but I don't want to get my hopes up I'm pregnant. I've been trying for almost 2yrs. I don't know when I should take a test, because I could have ovulated early. I'm probably just being stupid and getting my hopes up for no reason, but do you think I should take a test yet?
