I'm not sure if it's a hemorrhoid?

I don't even know if it's a hemorrhoid. when I push it back in all the way it doesn't come back out until I take another poop which is usually after 2 or 3 days. Also mine is small and I dont scream or do anything when I'm having the poop but just a little pain. Sometimes a drop of blood or sometimes nothing. I think I have a hemorrhoid only when I poop or maybe I just need a lot of fibre since I have the white stuff on my nails bt I eat fruit and vegetables so I don't know the problem. Once I had an internal hemorrhoid and I sometimes pooped then farted some blood ot. I just told my parents I have hard poop so my dad bought me the orage flavour fibre powder which you mix with water and drink. That cured my internal almost instantly in 3 days or so. I'm also 11 years old right ow so I appreciate if anybody has any information or help.
