my SIL is 13 weeks pregnant and she has myesthenia Gravis (Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. The name myasthenia gravis, which is Latin and Greek in origin, literally means "grave muscle weakness.") well she has to have plasmaferesis(A process in which plasma is taken from donated blood and the remaining components, mostly red blood cells, are returned to the donor.) so she has a catheder in her neck and her blood pressure keeps dropping just please pray the baby stays safe Thank you
