Advice please?

So I know I'm probably just getting worked up over nothing... But I was just wondering when's the earliest possible time to experience pregnancy symptoms.
Today I ate some orange chicken, and never have I ever had any problems with orange chicken, but I felt instantly nauseous afterwards, and it took a couple hours before it went away. And I am very bloated beyond the norm, on top of being extremely tired all the time, and very moody.
Me and hubby got it on last night and the night before, and I've heard a lot of women say they were having symptoms before implantation had time to happen, so I was just wondering what the likelihood could be...
