Hello Girls

I am 6 weeks 3 days pregnant as of today.

I am looking for some positive hope from the group. At 5 weeks six days I had heavy bleeding so rushed to er and they did blood work and found out hcg was at 20434 and next day they did scanning and found gestational sac. Dr. Said everything is good and didn’t find the reason for bleeding.They did not see any heartbeat though. I did blood work after two days the reading says 2960, is it possible to drop so much in two days? Has anyone experienced same please advise? Do I still have chance of having this baby?

TIA
