First Doctors Appointment

I called my primary care doctor's office a few days ago and explained my positive pregnancy tests I had gotten that week (and that I'm not exactly sure how far along I am since I tested positive a whole week earlier than my missed period). I have an appointment in a couple days, but will my doctor be able to tell me how far along I am? Or will she refer me to an OBGYN? I'm a first timer and I have no idea how this works!! It's agony to waaaait! (Also my primary care doctor has done my Pap smear before so maybe she has some Ob experience?)
