This morning Im lying down and can feel my heart beating in my stomach and its moving up and down slightly also for the past week ive been feeling popping/moving feeling in my stomach and all over my stomach. It literally wont stop and its scaring me. I can hear slight popping inside my stomach and feels a bit like someones punching or kick or poking me from inside of my stomach idk if its gas its lasted forever how do i get it to go away? What could this be?

I'm scared I'm pregnant but I'm a virgin I've only masturbated but because I used a metal bottle I'm scared it got me pregnant somehow.
