When to seek professional help?

So my hubby and I will be one year of ttc in February.  I know it is a few months away but I am curious about when and where to find professional help for possible fertility issues!  My thought is that around the one yr mark, I should make an appt to discuss my concerns.  Should I go to my Gynecologist (who is a midwife) or my regular doctor??  Any thoughts and experiences would be great :)
