is it possible to have an HCG of 41 at 1 or 4 weeks

Yexii • I know God will send me my rainbow baby someday :)
I was a couple days late and I decided to do a pregnancy test I ended up being positive but yesterday I have really bad pain in my back and in the front it felt like cramps. I went to the emergency room and they weren't able to determine how many weeks of pregnancy I had and it was a possibility that I had a miscarriage. I haven't bled the pain went down a little bit I still have some pain in my back but they said my HCG was 41 that for weeks it was too low but if it was one week it was fine I still needed to get more tests done. I'm going crazy I don't know what to think or expect or do I don't know if I'm okay I don't know if I'm not okay I want to be okay because this is my rainbow baby and I don't want to lose this one too. Any words of wisdom are welcomed.
