Depressed , Am I a pedo? :( please help

So, Im a 19 yr old female that stumbled upon child pornography on social media, I instantly reported the account like any normal person would do, but my curiosity peeked and I did see something that scarred me. Now let me say, Im attracted to males and female, my age, but lately Ive been seeing images in my head and thinking wrong about children, its almost if im traumatized by what I saw and I keep thinking of things that surround the subject, lately I tried to forget but it only makes me think about it more. In my thoughts sometimes I will say things like "I want to bleep children." But I KNOW THAT ISNT TRUE. Im not even sexually attracted to kids. its almost like another person is in my head and Idk what to do, I take birth control pills and idk if that matters but maybe its messing with me in some way? I absolutely adore children and would never lay a finger on them sexually or with the intent of abuse. Please help me, it's killing me..
