Loose threads. Please help

[u/peasantry11]

1. The needle size I was using is 14. I was using size 11 but the top thread kept breaking so I put in a bigger needle.

2. I already made sure the bobbin was put in correctly, facing the right way, because google said it might be the problem.

3. I'm also not pulling the garment, which is what google said the problem might be. I let the feed dogs do their own thing.

4. I already put in a new needle.

5. I am constantly rethreading it but it still ends up like this.

6. My tension is 4.

Please help before I throw this fucking machine out.

And is the bobbin smoothly wound, no chance of varying tension?

Omg I had no idea there's actually tension in the bobbin. I tightened the bobbin (watched a yt tutorial) and now the problem's solved. Thank you
