I had the same situation with my second pregnany. It should pass quickly however the sad feeling will stay with you for a while. I still get sad every June when his/her due date rolls around. Take a month off and try again, hard to be patient believe me we are working on #3 now and I hate being patient. However i can tell you i am so thankfully for the baby we ended up getting i know i couldnt live without and it sucked so back at the time but so glad for what we got out of it!
