I have two boys and am on the mirena coil, my dh mentioned a number 3 today and for the first time I agreed! With my second (was pregnant with him back in 2013) I was at 130/150 for downs, cvs came back fine. They then thought either my scar was rupturing or my liver was failing during my vbac.... I currently have the mirena coil so thought maybe the first stop was ask the doctors advice on the issues we had last time. Part of me is scared we will have high stats for downs again and can they tell if my scar is ok?
