I wouldn't count acne as a symptom of pregnancy that early and if it's the only symptom you have. If you think you are pregnant take a home test or go see a doctor.
I've had occasional pimples (1 or 2 at a time) and had been using acne treatments daily. Almost 3 weeks after conceiving (didn't know for sure if I was pregnant at the time) my face totally broke out. I mean constellation. I was freaking out as to the sudden outbreak. Well, about 4 days after the outbreak, I took a preg test and it came back positive.
