First Time Mommy

Iv taken 8 pregnant test all came out positive . I called my Ob to get an appointment wasn't able to get one to the 29th of this month . I went to get an ultrasound, at this place called the baby connection, I got to see my baby and the heart beat they said I'm only 8-9 weeks pregnant . Is it normal for me to worry about my baby , how he or she is doing? And should I be showing already?
