Heartbroken!

Felisha • Mom to 3 (including this baby) step mom to 4. I love our big family!
Back in February, my husband and I had a miscarriage. We had found out at 13 weeks the baby stopped growing at 8 weeks and had no heartbeat. Fast forward to now. I am 11 weeks and 4 days. I started bleeding so I went to the ER. Found out that the baby doesn't have a heartbeat (after I heard it at 8 weeks) and I am starting to dilate. Also, same with the last pregnancy- this baby stopped growing at 8 weeks. What is going on? Anyone else experience this before? I go see my OB tomorrow, I am praying we find some insight as to why this has happened twice in under a year.
