Can I go to the doc??

I'm 17 & have been ttc for a year now. I have irregular periods so it's really hard to pin point my ovulation. I want to go to a doctor but don't know if I have to be 18... Money is no issue. Btw I've graduated highschool, now in collage, engaged and have a place of our own, & both of us have good paying jobs. I know some of you ladies are judge mental as hell so I just put that out there. Anyways, could I make an appointment with my obgyn about ttc... I'm not sure because of my age.
