Once upon an infertile time....

I believe once you have fertility probelms you alway have fertility problems..with that said now that my monthly friend has returned so to does the question "what do we do"? It took us 5 years to get this little miracle who knows how long it will take again, and if it will even happen again. I am not so brasian to believe we will ever even get pregnant again, we want another child but I am also just so thankful for the one I have. Is it selfish to want another? Am I ready to go through all the worry and waiting each month to see what happens?? I know we say we will just see what happens and thats easy to believe BUT in the back of my mind it never goes away!
