Devestated

I was told yesterday that my baby has no heart beat and it looks to have stopped growing at 7wks. Except i am 9 weeks. The placenta is attatched and everything is where it should be except theres no heart beat and the fetus is quite small. This will be my third miscarriage in less than a year. I wasn't even trying to get pregnant this one just happened one drunk night forgot to use protection. Weve only been intimate with protection. I love my husband but i don't want to have sex for a while. Even with protection. I just don't want to be touched. Im so heart broken. The doctors don't know y i cant carry. All my tests come back fine. All his tests come back fine. My body for some reason is just fighting. My husband wants us not to have a dnc since for the last two i just waited for them to come out naturally. He still has hope that since it is attatched and im not bleeding that maybe the three sonograms ive had just cant read the heart beat he thinks maybe the babys small. His hopes are so high. I pray for a miracle. God let my baby have a heart beat and be bigger. Let it grow n live. But i know what the evidence points to. Today is Wednesday i have until monday to decide. What should i do?
