Fertility aids

Monica • My husband and I are 36 and 35, high school sweethearts, married in 2005, son Gavin born 11-27-15. PSU grad, work for small newspaper as a reporter.
Any recommendations on fertility aids/boosters that have worked for you? I'm trying to eat healthier and exercise and not get so stressed, but I figured a little something extra wouldn't hurt. I've seen mention of a special tea meant to improve fertility, for example.
