Girls, I have a question. A month ago, my EKG was perfect. Now they're doing and setting up an ischemic heart disease! Is that even possible? And in general, will they allow me to give birth myself? I know that my heart has never bothered me, but only maximum shortness of breath appeared during pregnancy. In general, can you advise what to do, because I really don't want to!
