What does it mean when i poop and it goes back inside me and i struggle to get it out then it's all bloody?

Hard stool: Hard stool may be irritating hemorrhoids or a anorectal fissure. Drink more fluids,take a daily stool softener and. if necessary, insert a glycerin rectal suppository for easier stool expulsion. See a gastroenterologist if there is significant rectal bleeding or troublesome bowel movements.

Keep it soft: Apparently your stool so hard and large it cut you as you are trying to get it out first reaction of the pain is to stop pushing so it retract back up and then because of the pressure you keep pushing until you get it out mixed with the blood created from the cut Keep your bowel soft hydrate well and try to go every day increase your fiber intake

Try fiber laxative: You may try taking a fiber laxative like Metamucil and drink a lot of water. If the problem persists, especially if the stool remains bloody, it would be prudent to see your doctor.

Constipation: It most likely means that you are constipated. You have a very large hard stool that has caused some tearing if your rectum. You need to have more fiber and liquid in your diet. If this is a one time episode of bleeding then you likely don't need to worry but I recommend you get this checked by your doctor to make sure.
