I would be wary of doing too much intervention before a year of trying. I took a year to get pregnant then sadly had a miscarriage and after another year of trying got pregnant again (first son) then got pregnant VERY quickly the second time around and had another boy. I did go down the route of fertility treatment before getting pregnant with my first son and found it extremely stressful. A combination of too much focus and all those hormones. If they say you're fine after the initial testing then I wouldn't rush into treatment. You could try acupuncture and Chinese herbs instead. I went this route in the end and got pregnant the second month (after 5 failed IUI's!!!) Good luck - I know how frustrating and disappointing it can be but you will get there and have your little bundle of joy.
