Miscarriage?

Stasha
I had my first ultrasound done last Monday. They measured me at 8w6d. They couldn't find the heartbeat. The tech Didn't look very long for it and I felt like the whole thing was Rushed.  My doctor wanted to do blood work to check my hcg levels. I had my blood drawn that Monday, But didn't get results until Wednesday. My levels were around 122000. I had more blood drawn on Thursday and just got the results today, 91,000. It Is a pretty significant drop. I've read that hcg shouldn't really be checked after 6ish weeks. And that they drop and level off after so long. I am being scheduled for a follow up ultrasound but I am devastated. We were ttc for almost 2 years. I don't have much hope and have been grieving since the ultrasound.
