Empty gestational sac but increasing hcg

I had ultrasound at 6 weeks and 6 weeks 6 days and doc saw empty gestational sac!! She again called me for a scan at 8 weeks 3 days to confirm blighted ovum. However I went for a hcg test at 8 weeks and level was 99000.

Anyone had similar experience? Is it blighted ovum for sure? I don’t want to keep hopes because last time I was hurt AF. And if this happened with anyone - what option you chose for miscarriage?
