Hcg levels

I got my hcg levels tested and they were at a 9 on Wednesday and then friday they were a 7. What’s weird is my pregnancy test came back darker than it did the day before. I’m a little relived because I just got an eviction notice today and have to be out tomorrow and I’m not sure where I’m going to end up or when I’m going to be in a permanent place but I’m also disappointed because I really want a baby.
