TTC seems like forever!!

Hi! I'm 29 years old and having been trying to conceive with my husband for over a year and a half! :( I was on the nuva ring for 2 years before stopping completely and now my husband and I are getting worried! We've tried all the "usual" recommendations and I've had blood work done to confirm I'm ovulating (which I am) and still nothing! Has anybody had an issue like mine? It is literally driving me crazy.. It's all I think about and wish for! Thanks!
