Trying to get preggers.... =(?

no luck so far.. been trying with my long term partner to get pregnant..we both really want a baby. we dont really think about it alot. liek we dont have just to get pregnant.. its more of a fun thing. why arent we getting pregnant..im to scared to go to my doctor because he thinks im too youg (turning 18) he frowns upon this. always trys to tell me to get contraception and stop trying. because we are too young. we rae financially stable enuff for children and would realy like to have a baby together. have been together for like 5 years. have been having for a year and nothing yet we dont wear protection of course or use lubricant for ..any ideas on how i can get pregnant soon. my sister suggested clomid the treatment for polycystic ovary syndrome but bcause im to scare dto go to my gp i dont know if i have it i know you can only get it thru prescription but he wont test me for it with out the issue of pregnancy arising to him.. any natural ways you can suggest.?
