Is this a yeast infection?

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​I wanted to know if you guys think I have a yeast infection. I was making sure that my vagina looked okay but I saw a white substance in my vagina. I have no idea since if this is a yeast infection this will be my first.
