Passed baby

We found out today that our babies heart had stopped beating. I'd be 9 weeks and 2 days. I planned to go in tomorrow for a d&c so we could do testing on the fetus to help determine why I keep miscarrying. When I got home a rested a bit then got into the tub. I began having what I can only imagine are contractions and it was excruciating. After awhile I passed my baby. It was awful and I'm devastated for the loss but also upset bc now we can't do any testing so I feel like I'm doomed for this to happen again!! This was so traumatic.
