Itchy! 😭

hi guys, so my clit has been itchy for the past few weeks but nothing too bad. I thought maybe something irritated it and it was reacting to it so I gave it time to subside and changed my detergent. it stopped for a little while until last night where the itching was unbearable. I'm thinking it is a yeast infection, but no other parts of my vagina are itchy. do you guys think that's what it is? Because I do and I plan on picking up medicine for it today.
