Burning Vagina 😬

This is kind of embarrassing but for the past 3 days my vagina has been burning when I pee and it feels worse in the shower . After I pee the burning doesn’t go away for a while especially when I pee after a shower. I’m only 15 so it can’t be anything super bad right ? I’m scared to tell my mom but it’s really bothering me to the point I cry sometimes after showers.
