I am so sorry you are going through this

Did they happen to tell you if your cervix was open or closed? I really dont know.
At 7 weeks, your baby should have had a heartbeat, unless she measured wrong and the baby was under 6ish weeks. But is it possible for you to only be 6 or 7 weeks pregnant???
I REALLY hope and pray it is NOT a miscarriage!!!
