TTC Doctor Appointment

I have been trying to conceive for a while now and I'm curious about visiting a OBGYN. I don't really have a OBGYN doctor, I've just always seen my family doctor for birth control Etc. How long do you have to be TTC before clomid is prescribed? Also, do I just need to to make an appointment with an OBGYN to see if everything is okay? I feel like I'm not getting anywhere TTC on my own.
