hello, i have been taking oxyelite pro for about two weeks to lose weight . A couple days ago i had blood in my stool , When that occured I was using the bathroom for a while. then tiday i sed the bathroom and it didnt hurt but there was blood again. Last year i had blood in my stool because i had severe constipation . but i assumed the tearing healed already. I dont belive that it is an ulcer because my stomach does hurt and i am not in any pain. Could it be due to not drinking enough water or a lack of fiber intake?
