11 weeks for first visit?

I should of set up appointment right when I got my positive but, after choosing a birth center and ironing out insurance we finally made an appointment at 9 weeks and they can't get us in until I'm 11 weeks. Is this ok? I feel pretty good aside from normal 1st trimester symptoms and take my prenatals but, the only "proof" of pregnancy is my positive test and absence of period. It's scary!
