Gestational sac and yolk but no baby

LL

I don’t know how to feel. I think it may be bad news for me. Went for a scan follow up about 2 weeks after an ER visit where I had slight bleeding. They only saw a sac and a yolk then too and all they could say then was I measured 4 weeks or less than 4. They took my hcg blood and I got 2411 then checked it again 2 days later and was 3894 which they said was a good sign. I’m still feeling breast tenderness and bloating. I was heart broken to see there was no baby yet but dr said there could still be a chance but it didn’t look good. She said miracles happen. I have to come back in 10 days. I don’t know what to do with myself.
