HCG level?

Julia • pcos | just trying to find myself again 💖

I finally got my blood test results. I am infact pregnant but my hcg was only at 31.

According to the app I'm currently 6w today so at the time of the blood draw I would have been 5w. The nurse told me that level is kinda low but I could be earlier in my pregnancy than I think. So I'm going tomorrow again for another blood test.

Should I be worried? Is that low?
