Yeast infection?!

Lately it's been burning& feeling dry & when I was a kid it'd feel like that and I'd put Vaseline and I'd be fine but I checked myself out today and saw a lot of white stuff , I'm clean I clean myself well so it's not like I'm dirty but it looked like this really weird discharge with white stuff so I'm assuming it's a yeast infection how do I get rid of it it really burns and is a little bit red and irritated now because I thought it was regular discharge that I tried getting rid of but its still there. Help me please!
