need advice .. empty sac at 8 weeks

Alexis
So yesterday I went in for a ultrasound they seen a empty sac. At first my hcg levels were at 7500 then 7200
Something like that. Anyways they seen no fetus no heartbeat. My midwife refuses as well as I do to jump into things and do a d&c she's waiting two weeks and seeing if anything goes well at another ultrasound... She said she's had women have this happen and in two weeks it's all positive. I have little hope and need to know if anyone's been through this :(
