Hello, 1blessedmom.ap, I hope you did not have to have any episiotomy during your latest childbirth. Your description of very hard stool and straining at stool followed by passage of blood , really limits the site of bleeding to the lower ano-rectal area. You mention about a tear or a fissure. Usually with this there is a lot of burning pain and the tear is located at th end of the anal canal. In your case, most likely you have internal hemorrhoids, that is not visible or felt by touch unless they are prolapsed or protruding. This can happen if a person continues to strain and is severly constipated. Make sure you start taking a stool sotener daily at bed time 1-2. You can find them in any drug store. You can buy a hemorrhoid cream containing 10% hydrocortisone and a local anesthetic. Using a finger cot apply a small amount after a bowel movement. You can use this three or four times a day. If the bleeding does not stop, then you may need to see a proctologist who can do a sigmoidoscopy to check the rectosigmoid area and treat appropriately. It is possible that one could have a polyp low enough that could bleed. This is doubtful. I wish you well.
