"superhuman smell" during pregnancy?

Well, I got up this morning and my DH was in the process of making coffee. When he opened the lid to the coffee can I could smell it across the room, (kinda made me queasy). Also last Saturday I was sick and feeling lightheaded and I know, tmi, but my pee smells stronger.YUCK. I'm not supposed to start until Sunday. Could I be having these symtoms this early, if indeed, I am pregnant?
