Yellow CM

Hey so I don’t normally do this but I’m a little weirded out. I’ve been tracking my CM as religiously as possible. Before I started using the app, I still made note of it. Today I had a yellow, almost sticky CM and I don’t know why that would be. This has NEVER happened to me before it’s usually always whiteish, cloudy, or clear (sorry if this is TMI)

I was just wondering if this has ever happened to anyone else before? I’ve already ovulated so I don’t know if that might have something to do with it? Please help me out! Thanks!
