Fertility Treatment

So I have been trying to conceive for over 1 year and a half with my boyfriend and we keep on getting BFNs. I went to my doctor mid 2014 regarding this and I just went there today he said I had never come to him regarding this which is a lie, so now he is saying I need to follow some guidelines (British Fertility Society Guidelines) he has asked me to just keep on trying etc... That's couple's need to be together for a certain amount of time etc I thought he would have just given me the medication but for some reason I feel like he just does not want be to conceive for some reason.

Do I really need to follow any guidelines? I'm not looking for ivf or anything.
