need some reassurance

Jennifer
11 weeks today, Dr appointment on the 16th to listen for the heart beat but all of my symptoms have just gone over night. Normally I get nasuses all throughout the day, can hardly eat, smells bother me, headaches & just none of that all day.. it's silly to say I feel SO good that I feel like something is wrong.. 
no cramps, or bleeding or anything. Just feel like a dr will laugh at me for saying "I feel good so I think something is wrong" just wanna know if it's normal/:
