Best time to see a fertility specialist after trying to conceive for a while

“So I know you’ve been trying for a long, for a while and you’re wondering, when should I see someone like myself? Well, basically if you’re under 35 and you’ve been trying for a year and just having sex at least once or twice a week, then you should come see. And if you’re over 35 and you’ve been trying for about six months, then you should probably contact someone like myself.”
