A bit worried

Hey beautiful ladies, 
Am a bit worried am 5 weeks and 5 days along ....  I feel like my stomach is not growing and I don't see any change in my body besides my breast! I have a doctors appointment on the 19th but I'm a bit anxious . In the last couple of days I was lightly spotting is that good or bad ?
I have a feeling am not but I took over 8 pregnancy test and all of them are positive !!!! Am I going crazy
