My structure & color are different from others. Is this still a mucocele?

I have been looking @ posts & articles on mucocele but mine is very different. It's like a dark & thin blood clot. Sometimes it disappears (depending on diet?) after 2-3 days, but this time around, it's been up almost 2 weeks. Can anyone offer an identification? Thanks.
