HCG too low?

I got my positive test yesterday, still quite faint but it’s there. I called my EPU since I have a history of ectopic and miscarriage and they got me in for a blood test. They just called and said my levels are 254 which is quite low. I don’t know if she’s referring to it being too low to scan (I know they won’t even attempt a scan if it’s under 2000) or if it’s quite low for 4 weeks? I’m driving myself crazy here 😢 can anyone please share what their levels were and if they were ‘normal’? Or just some gentle words would be appreciated! Thank you and baby dust to us all ✨

Edit: I go back on Wednesday for another where they want to see my levels double 🤞🏼
