I went for my 20wk scan on Thursday and baby is growing fine, but they found that he has a mega cisterna magna of 9.3mm and 4 holes in his heart. We wasn't really given any information or advice just that we needed to come back Tuesday for a scan with a cardiologist then sent on our way confused and terrified his going to die. I'm so scared and have so many questions. I already lost a baby at 24wks due to placenta abruption and have had multiple miscarriages this baby really is my miracle it's taken 14years to get pregnant. Has anyone had anything similar? I've googled and I can't really find any answers. I don't know how we're going to get through the next few days we just keep breaking down and fearing the worst.
