Mouth burns!!

Kristi • Saved by The Blood of the Crucified One! Glory Im Saved!
So I had some hot pizza. 
And the roof of my mouth got burnt.
I knew it was hot but it didn't feel hot enough to burn me while I was eating it until I got halfway through the slice!
Then right behind my front teeth on the roof of my mouth, a little layer of skin peeled off and now it feels raw! 
It burns really bad and especially when something touches it! 
Can I put something natural on it? I have a few young living oils and some apple cider vinegar and things like that but I'm not sure what to use.
I'm also 4 weeks Prego! 
Thanks!
