Over 1 year ttc no luck, what's next?

B
Do I contact my gyno office for testing or do I contact a fetility specialist? What tests do they do and what is it like? I want to have myself and hubby checked out but don't know where to start. I'm feeling defeated and know he is too. We're both 30 this year and wanted to have our baby by now. So many people we know are getting pregnant. Help please :)
