Fine lines running through Image

[Brittanie29243221h2jx]

I'm working on a post for instagram but every time I save and export, I get these fine lines running through my image. Why does this happen?

How do I get rid of those fine lines through my lettering?

What operating system? What version of InDesign? What settings are you using to export to what filetype? Are you working in RGB?
