Yellow discharge... yeast infection? STD? See pic

Hey guys, sorry for the TMI here, I don’t have a doctor appointment till

Tuesday so I’m freaking out. I had what I thought was a yeast infection over the last few days with a lot of discharge, the itching has subsided a bit but not all the way.

Have any of you ladies had discharge that looks like this? Was it an STD? Yeast infection? Bacterial vaginitis? Or just normal?

Thanks SO much. Any and all help appreciated.
