I do not quite get the scenario where you have not been to europe but are now going there to have surgery that is already scheduled. I second and third RadioGirl's advice, there are some specific and good rules to follow after any procedure. As an additional note, the airline can refuse to transport you if they do not like your condition (far into pregnancy, look ill, drunk, etc)
