Chemical pregnancy...

Cassie
On December 21st I got 2 BFPs. The 12/22 went to get blood work and it came back positive but the count was really low. 12/24 I started spotting (pink). 12/25 I was having bright red blood flow. Does this classify as a "chemical pregnancy" or a "miscarriage"? Can anyone explain the difference? Either way me and my husband are super upset. Also, how soon can we try again?
