HCG level 26

My hcg level is at a 26 as of 1pm yesterday. I had a miscarriage on April 30 and went back in on May 17 to make sure my levels were at 0, which they were. So 3 weeks ago tomorrow they were 0 and yesterday they are 26. So obviously I didn’t ovulate when I thought I did.. Is this level concerning? Or is it just that I caught the pregnancy very very early?
