Pemphigoid Gestationis is a rare autoimmune blistering skin disorder that affects an estimated 1 in 40,000-50,000 pregnancies in the United States each year. United Kingdom figures put it at 1 in 1-2 million people. You could say that each of us is one in a million! No one wants this; most have said that they wouldn’t wish it on their worst enemy. This is my PG story.
