Negatives

It's so depressing, we do everything like we are supposed to and are trying so hard. But all I ever get are negative tests. I feel like pregnancies is never going to happen for us. My doctor said after my surgery (had a wall removed from the middle of my uterus and all of my endometriosis removed) that I should have no problems. I'm so sick of hearing "relax it'll happen" "quit stressing" "have more sex", but its not that freaking easy. With each negative test, I get more and more depressed. Will I never have my rainbow baby? Or will I always only be know as a mother with a child in heaven or for some, not a mother at all?.....
