How long before I should get help?

I was diagnosed with PCOS about a year and a half ago and we've been trying to get pregnant for about that long too, and no success on any of the medications (metformin, clomid). I don't have normal periods and never know when I ovulate cause I'll think I ovulate and I really don't. So I'm wondering how long before I should get some help. I'm only 24 so I feel like I'm not there yet to have to see specialists?  Or maybe they'd be able to help me more than a regular OB. Praying 2017 is our year for a baby 🙏
