Has this happened to anyone eles

So found out I was pregnant on 13th April my hcg levels were low an not rising as they should so they told me was ectopic pregnancy so t Dr sent me to get the shot methotrexate. My hcg was 32 when I got the shot a week later got blood work done an my level went to 23. I'm not understanding why it's taking so long to go back to zero. It's very frustrating
