Speech pathologist here, feel free to PM me if you have more questions. Since she has some words and just turned 2 it is not a major concern, the concern would be if she is not using a lot of gestures (pointing to things she wants, waving to say hi) and showing understanding of your gestures. Those types of things would be more concerning because they are signs of autism.
I'm in California so I don't know the NC systems but there should be a birth to 3 resource for you, here we call them regional centers that you can contact and they will listen to your concerns and if necessary do speech assessments and psych if necessary (for free). Many pediatricians don't know much about language development so if you can get an assessment without waiting for a referral that would be good. For a two year old, speech therapy would mostly consist of the therapist teaching you techniques. I have some good documents at work I can send you that detail some techniques to use in parent friendly language. So PM me your email address if you want.
