Hi..welcome to the forum. It sounds as though the bleeding could be hemorrhoids (if you have been checked out) with you also having IBS and constipation.
Have you seen a gastroenterolotgist (GI specialist) or an anorectal surgeon?
Are you on any medications at this time?
Do you drink?
Do you smoke?
What other medical maladies do you have?
What is your daily intake food-wise like?
Are you male or female?
Not that we can diagnose on here....but more information can help with suggestions.
