Ttc for 6 years

Heather
I have been ttc for six years with thousands of not pregnant tests and even more friends family and co workers anle to have more then two kids. Why cant I? I don't understand, Dr's say everything is fone with borh of us... I even seeked a second and third opinion. Anyone else woth these problems that either had a kid or pregnant now. I need to know there is some sort of positive outcome that can come of this.
