TTC Help!!

ok so I have been trying to conceive for about 7 months now. I am taking Preseed, my iron pills, my prenatal a, drinking more water and eating more fruits and vegetables and still nothing. I am planning on just calling my Doctor and setting an appointment to help me TTC. I know that the least amount of TTC is 1 year. Would it be bad if I just tell my Doctor I have been trying for a year now and still nothing so he can help me? Any tips on what helped you guys conceive?
