My SO and I have been trying sine Aug 2015. I know it's not very long but we've done all the tests and they have all been normal, we've done opks month after month, I've pee'd on stick after stick, we've done preseed, and even clomid and nothing.... it's frustrating....my doctor says there is no reason why I shouldn't be able to conceive and yet..NOTHING! I'm honestly getting discouraged...
