Advice for new couple TTC

We are going home! My job has finally led me back to my hometown and the county that both me and my husband grew up in. Now that we are going to be near both of our families we want to start our family. We have had unprotected sex for the past 3 years with the mind-set "if it happens, it happens." Obviously it never happened, now I am asking for advise. What works? What brand of opk works the best/easiest to read? What else works? Thanks in advance!
