Like BigJ, I went to IM for DE treatment & can honestly say they were more thorough, understanding, helpful & friendly than the clinics I was registered with in this country.
The first treatment produced a +ve result but it turned out to be a biochemical pregnancy, the second (FET) was unsuccessful but after the 3rd go I am now 8 weeks pregnant with twins.
I'm sure BigJ has told you, they now have an english doctor, Victoria Walker - who is absolutley fantastic, so any queries you may have regarding technical terms in Spanish are no problem.
And on top of everything else, Barcelona is a lovely city to visit.
BigJ - hope you're getting on ok with the patches, just wait until the treatment works and you have to have one on each cheek

My bum now looks like a pepperoni pizza
Good luck with the endo scan.
Love
