Hi @Pedro_Gabriel ,
Welcome to the community and I appreciate you reaching out for help.
I understand that you are having concerns with the increasing cost of your BigQuery services. A few possible reasons might be causing this; 1. you might have scheduled queries running in the background and 2. there might be other users/ members in your project who are utilizing your queries, tables or datasets.
One quick way to control this is to restrict the number of bytes billed.
You can limit the number of bytes billed for a query using the maximum bytes billed setting. When you set maximum bytes billed, the number of bytes that the query reads is estimated before the query execution. If the number of estimated bytes is beyond the limit, then the query fails without incurring a charge.
You can also review these resources to further your understanding with cloud pricing.

Hope this solves your problem.
