Coping with lost! 😭

I was having contractions last night so we decided to call hospital and told me to go down there in the emergency care. Went there they check for bub heart beat and couldn't find it they brought us to the room and did another ultrasound but bub had no heat beat anymore. We were devastated. We cried for hours. How could this happen when everything about the pregnancy was perfect. I'm so heart broken right now. He supposed to be 37 weeks this week!everything is ready and waiting for him at home!
