Terminating Pregnancy

I am so devastated and wish I had another option. I feel like a failure I have had 2 losses and one healthy baby girl. I am currently 18wks 5 days I went for my anatomy scan and was told i have Single Umbilical Artery(SUA)...also was told baby has Chorid Plexus Cyst(CPC) & lastly was told they cldnt measure the heart. I am just so helpless right now and I can't imagine bringing someone into the world that may suffer. Makes me never to want to try again and stick with just our daughter.
