I found this stain on my ceiling and I'm wondering if it's water damage. It's been there for a while, but it hasn't expanded at all. Here's a link to the picture of it: https://imgur.com/a/3CchkhQ. Any ideas on what it might be?

It’s probably not water damage since it hasn’t changed much over time. Have you noticed if it was there before? Sometimes stains can come from other sources, like previous leaks that have dried up or something more unusual.

Thanks! Do you know what other sources could cause such a stain? It really looks strange!
