questions?

Natalie
I just found out yesterday with a test that was positive! (I am excited!) I'm going tomorrow to my doctor to tell them. Will they be able to give me a test without an appointment to solidify the positive take home test or will I have to wait? 
Second question- when does morning sickness usually start? I haven't had any and according to what I am pretty sure was my concierge date, I'm 4 and a half weeks along. 
Thanks!!
