How to deal with having a miscarriage?

On May 1st I was 6wks+2 days along(first pregnancy). That afternoon I began spotting lightly (I know it's common) so, I called my doctor's office. I was told to monitor the flow and keep the doctor updated. That evening the flow became heavier, large size "jelly" chunks, and cramping (sharp constant pain specifically on one side). Called the doctor again and she confirmed what I knew that I was experiencing a miscarriage. I went to the ER the next day. It wasn't very helpful but I did find out my blood type which was important. My husband and I are still processing what happened and wish we had an answer as to why this happened. I feel numb now. We are still grieving but doing okay. I know that this is a sensitive issue put this is the only place I feel comfortable talking to someone about what I'm going through.
