Yellow smelly discharge

I’ve been worried about my discharge recently and most of the time it’s yellow with a nasty smell, I have no other symptoms and I’ve done a home kit for infections and my pH balance is normal. I do not have any itching or burning sensations either. I looked on google but there’s not that much that helps me.

I’ll be booking a GP appointment soon but I’d like to know if anyone has experienced something similar and what they went through to treat it, etc.

Thank you.
