Miscarriage test

Loriann
Im so confused and upset. I recently had a miscarriage and had to have a d&c done last monday. They sent off the baby to test it. My dr says the pathology report came back normal but the chromosome test couldn't be completed because there was not enough fetal tissue. Basically baby was too small. I was 6wks when babys heart stopped after seeing it beating at our sonogram. Previously a year ago we had a blighted ovum. Im just so scared that something is wrong with me or my husband as far as our compatability or chromosomes.. any imput or advise or experience in this would be greatly appreciated 😢😢 idk what to think. I just want us to finally have our rainbow 🌈
