Starts over: It's encouraging that you been able to conceive before. Unfortunately when conception is not easy the second time then further evaluation needs to be performed. Hormonal evaluation such as TSH and prolactin and mid luteal Progesterone with be helpful. A semen analysis will also be helpful since those parameters can change after three or four years. An hsg will be helpful also. Causative factors for secondary infertility are the same as they are for primary fertility.

Consult time: Sources quote an average of 6 mo trying prior to establishing a pregnancy. Most would not consider a fertility issue involved until you went 1yr without success. A discussion with the OB and a referral to a fertility center may provide you with more information.There can be issues with either party in this process.
