First prenatal appt today! NERVOUS!!!!

Olivia
For some reason I am SO nervous. I feel like this is all just so surreal and like I'm going to be told that something is wrong. Did anyone else feel like this before their first appointment?? I have take pregnancy tests like every couple of days for the past two weeks because I'm paranoid and every time it's like BOOM. Immediately positive.  
Should I be this nervous??
