Anybody with HCG over 5000 had an ectopic?

Hi,

Doctors are currently doing repeated blood tests because I had an ultrasound that showed what is either a luteal cyst or ectopic, they can't tell. I had an empty sac on in my uterus that OB thinks may be a pseudosac. I have spotting and bleeding, no pain, and low progesterone. I'm 6.5 weeks and my HCG went from 3900 to 5500 in 48 hours, a 66% rise. They've tested it again today and it dropped to 4700.

Anybody who ended up having an ectopic with HCG this high, or should that reassure me it's probably intrauterine?
