worried about fertility

hi I am 22 and my boyfriend is 26, we have been together for just over 2 years, living together for just over 1 year. have dealt with money problems and moving house twice and are still going strong. we have always talked about kids since our 3rd date maybe.. I have always wanted kids young and he is getting older so we decided to start trying in March last year, however I think it tane a few months for my cycle to regulate. It has now been about 9 months and we still aren't pregnant we are still young so didn't think it would be a problem.. although as time passes I am worried about fertility. Anyone else in this boat? Or know of any natural remedies to help things along. I don't feel comfortable yet taking any medications or going to see a fertility doctor will give it at least another year or 3 2 before considering that. but would happily try natural home remedies if there are any? Thanks in advance x
