Can't get Pregnant

Me and my boyfriend have been together for 2 years now . Since we've been together no protection was used him and I both have been to the doctor and have been checked and are Safe . I'm not pregnant yet , yes I want to be . But it maybe the wrong time in our lives as some people say . But I really have Baby Fever and want a Baby and tips ? It emotional gets to me talking about having a baby or even trying to anymore .
