Possible miscarriage

So Im 10 weeks and 4 days and I’m 17. I started spotting so I went to the hospital, the baby’s heartbeat was fine, my cervix is closed, but my HCG levels dropped from 197,000 to 161,000. Please someone ease my mind because I’m freaking out. I do not want to lose this baby.

UPDATE: went to the OB this morning baby was growing fine and healthy, heart rate was 158. She told me it was normal for your HCG levels to drop and even out.

Thank you for everyone’s thoughts and comments! I was so worried.
