TTC, Help? Suggestions.

I'm 23 years old, was previously on birth control for about 6 years. Quit taking for about a year then was going to go back on it was on for about a month again then decided to stop taking due to breast tenderness, and I was always tired. Plus weight gain and nausea. Around the time I stopped taking it most recently happened to be this past January and my SO and I have decided we both would like to try to have a child. A friend of mine suggested trying to talk to my doctor and my SO suggests I wait.. we have been trying for about 6 months or so and no luck. Don't know if I should consult my doctor or wait and keep trying. I know some people it may take years before getting pregnant. I just would like some opinions, thoughts, suggestions.
