Fertility drugs/treatment

Veronica
What stipulations do you think should be met before a family seeks <a href="https://glowing.com/glow-fertility-program">fertility treatment</a>? 
i.e. A certain length of time TTC? Certain time frame of charting bbt/periods/etc? 
Certain amount of intimacy each cycle? 
​After months of testing eggs/sperm/etc? 
​Are there any real stipulations?  
​If you haven't conceived in a year of trying is it okay/do most doctors let you resort "immediately" to fertility drugs?
