When to seek help?

Hi ladies! I currently do not have an OB doctor, as mine moved her practice to Florida. 😞 The soonest I can get in with the new OB I want is July. My husband and I are both in our late 20's and have been trying to conceive since January with no luck. I know it's only been four months, but should I wait for my July appointment or should I see a doctor sooner?
