TTC 1 when should my first Dr visit happen.

TTC #1.  I'm 34 yo. Month 1 nothing, just starting month 2. Started Glow so I can know/track my best days. 
Do I absolutely need to go to the Dr before? Or can I just wait to see if we're even able to conceive first. We've decided if it doesn't just happen naturally we're ok and would not do extra medical things to conceive. Guess I'm wondering if the Dr does something special at this point or can I wait till I conceive to go?
