Database bandwidth limit on free plan

I am using convex db for my project. I'm still in the development phase. I have three test users in the application and I'm getting a warning notification saying that I'm already exceeding the database bandwidth.

Just wondering if I've configured something wrong or this is normal? I expected to upgrade to a paid plan when I actually had like 100 paying users at the very least...

Is there a reason that my reads are so high? Is it because of some potential error in using the useQuery hook? (auto realtime)

Thanks
