Hcg levels

Did anyone on here have their hcg levels taken by bloods in early pregnancy? If so what were your levels?

I found out on Wednesday I’m expecting but am high risk of ectopic and was experiencing pains yesterday so went hospital. They did bloods and advised me my levels are too low for a scan just yet so more bloods to be taken Tuesday. The lady on the phone kept saying about they don’t rise any more then it could indicate problems so now I’m worried as she made me feel like my levels are already low..?

My level was 683 and I believe I’m 5 weeks and 1 or 2 days 🤷🏻‍♀️ thank you for reading☺️
