Not really sure where I go from here

So E has come to terms with the fact that we may never have any more children. I sadly have not. After 5 unsuccessful rounds of clomid, 1 failed IUI and lots of uncertainty I feel like I don't know where to go. I wonder if I am pursuing another child because of all of the babies I have lost. Do I really want another child or do I just think I want another child because those opportunities have been taken away from me. It will be 2 years in July that we have been TTC that third child. My last bfp was in December 2007. I think I have to find a way to let this part of my life go. It makes me sad.
