question about D&C

Briana
I go Wednesday to do another ultrasound which I dread because it will take me right back to the day I heard the bad news that there was no heartbeat & I go Thursday to do a D&C. Well my question is after they do the surgery can they find out what possibly happened to my baby as in to why he or she stopped growing or why the heart stopped beating. I just wish I could get some kind of answer to what happen or why it happened especially because I heard the heartbeat at 7 weeks and 5 days and the baby stopped growing and the heart stopped beating at 8 weeks and 5 days and I would be at 10 weeks and 4 days as of today so when I go for my D&C I will be about 11 weeks & 1 day. 💔 thank you!
