Jo, just remember that everyones situation is different and where you posted is the correct place for the ??? raised. It certainly has been very difficult emotionally and phyiscally with the MC's and time wise for me to fall pregnant with no4. I would hate to be starting at this age (40)otherwise this definately would not be an option. The feeling does'nt go away, I tried to fight it for a while, whether it is the biological clock ticking, saying this is the last chance who knows???? But it is a very strong urge!!!!! Starting to try again sooner rather than later is a great idea, your baby will be a nice age when the next one comes along. Heaps of luck to you.
