HELP ASAP!

I am having a white-yellowish (mostly white) discharge, it’s lumpy, it’s inside the vagina (the conduct) and the outside is itchy.... it’s a bit swollen, you can’t see it but I feel it (it’s my body, I know when something is different) and I really don’t know what it is, I was hoping to get some opinions before assuming anything, and of course I’ll be going to the doctor this week, I just want to have an idea of what it is, but like for real I’m worried 😭

UPDATE: it’s not smelly, it doesn’t even have a strong smell....
