HCG! Worried!

Kenzie
So I went in to the ob Friday due to some light bleeding. And of course they did a pregnancy test that was positive. They then sent me for the ultrasound because they estimated me to be about 5 weeks. Nothing showed on the ultrasound. They said it could be too early. Or a possible ectopic pregnancy. They did labs and my HCG count was 802. I went again today for HCG test again. Waiting on the results.. but I'm worried sick because of the ultrasound and the hcg.
