Hi there!

Well, that is a good thing that your tests have all come back normal! And you have DS, so thats a good sign as well (you know that you can get pregnant) Hopefully you'll get you're BFP soon!
My DH and I have been trying for 18 mths. We started seeing an RE after 11 mths and discovered multiple problems. Its discouraging when you continue to get additional bad news each time you have a new test or procedure, plus seeing AF each month.... but, I can see why it would be frustrating in your case too... IF just isn't fair. Welcome and best of luck!
