So i recently got kicked in the vagina, really hard! It fucking hurt

Now my 🐱 is quite sore as expected and a tiny bit itchy 🙈 i think (not 100% sure) that the sides of my vajayjay are swelling ?? And im scared its not because i got kicked and i have an infection? I cant be std's bcs i'm way too young and never done anything to cause them if you know what i mean. I am also slightly dehydrated so could that make it itchy? And it is wuite dry at times? Do i wipe to much/hard?? Help?
