Help! Question!? Worried!?

Last week, I had a u/s done due to abdominal cramping and they diagnosised me with a ectopic pregnancy and I was in surgery with an hour. Short story, it was not ectopic just a hemorrhagic cyst. However, they did not see anything via u/s in my uterus at the time because they said I was too early.

Went back yesterday for a follow up and they saw a gestational sac via ultrasound but nothing else. They drew my labs and made another u/s appt for Jan 6. However my labs came back today with hcg 10,917 and progesterone 15. The nurse said sometimes it takes longer to see a fetal pole or heartbeat but everything I read says "blighted ovum".

Dates:
LMP 11/15/13
Ovulated 12/2/13
BFP 12/15/13
HCG 161.8 12/16/13
Surgery and nothing on u/s 12/19/13
Empty gestational sac 12/26/13
HCG 10,917. 12/16/13

What do y'all think?
