Is it normal?

Elizabeth

So monday last week i went to er because of pain and i had hpt that said i was pregnant and the ultrasound showed nothing and my hcg level was 369 and so i went to the doctor on friday and had blood drawn and i got my resulte today and mu level was at 1,774. I feel like thats a huge jump or is it normal? I have to redo it tomorrow which i think is wierd or is it normal as well?
