Possible yeast infection

I’ve never had a yeast infection before so I don’t know what it’s like.

It’s been sore, swollen & itchy down there, my discharge is cottage cheese like. It just hurts like hell.

Is it possible that I have a yeast infection?

I last had intercourse on June 8th with my hubby & then got my period on June 12th as normal. Is it also possible I’m pregnant?
