Boyfriend feeling like a failure

We been ttc for months to close to a year n no luck he asked me if he was doing something wrong I said no it takes time it takes up to a year he cried saying he been trying he want a family he ready for a family all I can do is sit there hug him n cry with him n let him know it’s going to come one day

Should I try using pre-seed what should I try next month cause this month my period just came on
