What is deformed gestational sac?

Tipishtapish

I had a miscarriage (blighted ovum) last month (12/16). My hormones were back to normal in two weeks and everything was cleared. Two days ago I took a pregnancy test and it was positive. My doctor told me to do an ultrasound. This is my report. My beta hcg is 101 mIu/ml

I am really scared of another miscarriage. Is it too early for the gestational sac to be formed?
