There is a small amount of data about pregnancy after stage 3 diagnosis. Here is review paper. It seems that pregnancy after melanoma diagnosis is not linked to worse prognosis.
Maybe you could try Poland? As far as I am concerned immunotherapy with ipi/nivo/pebro has been approved in Poland. The best place to start in my opinion is prof. Piotr Rutkowski from Maria Sklodowska-Curie Memorial Cancer Centre and Institute of Oncology, Warsaw, Poland. He is the best melanoma specialist in country. Write him an email (rutkowskip@coi.waw.pl). Usually he respond very quickly.
