Hi nono_1890, 
I have the same problem the only difference between us is that in my case the second medical will expire last july not the first one

but I do not want to do it until they ask
on 15 july 2011 they asked me to redo it and look it's almost a year now and nothing
on the mail they said the processing time will take at the most another 6 month but nothing after 11 month
I will finish 18 months after days ;D
also do not forget the new law
but it is up to you
