9000 hcg no fetal pole

Courtney • Hello I'm Courtney, im 27 and am expecting my first child with my fiance Eric. Praying for a smooth pregnancy and a healthy baby! Look forward to interacting with you all! :-)
I just received the news that at 5 weeks I'm only at 9000 hcg and they couldn't find the fetal pole. I was asked to come back in 3 days to check on my hcg levels... I'm beyond worried and can't think of anything else. Has anyone else had to go through this? This is my first pregnancy :-(
