When to see Dr about TTC

Kala • TTC #1
After doing absolutely everything on our power the last 7 months (good diet, gave up booze, one coffee a day, opks,prenatals, preseed,temping, etc...) we have yet to get pregnant. I am in 2WW now and just so nervous it will be another dissappointment. How long should I wait before going to the Dr? She mentioned after a year to come in for tests, but that seems like forever, and I am 33 and feel the clock ticking. ... I also don't want to jump the gun. . Any advice or words of wisdom? ?
