Yeast infection HELP

It’s only the second day and it itches so bad!!!!! I can’t get anything done. And I have a lot of cleaning to do today. I’m 17 I don’t have a license and my parents are away until Monday. I ordered vagisil on instacart. It doesn’t work. I guess it kind of made the itching go down but I can’t tell and now it BURNS and itches. What can I do to make it stop?!??! I read online that Greek yogurt works. I tried that yesterday it did relieve it temporarily should I keep doing that??? Idkkk it’s soooo friggin uncomfortable right now.

Is this something you need to go to the doctor for?
