Thin with PCOS

Hey ladies, just wanted to see if anyone who has had PCOS and is on the thin side has had success with ttc. I've been off bc for over a year now with cycles from 56-130 days. My doctor ran blood work and said my insulin levels are fine, so what helps most women with PCOS won't help me. I'm not seriously underweight, I'm 5'7" and about 130 lb. Just wanted some words of encouragement and any suggestions to help ovulate more frequently. Thanks!
