### Human:\nis it possible for my miscarriage to have happened wothout my knowing. i am about 5 weeks pregnant but have steadily been feeling a decrease in pregnancy symptoms. i have also had a lot of cramping. yesterday morning i passed what seemed to be a lot of dried blood. i have also been passing small spongey pieces of tissue. the cramps come and go but my lower back pain is getting worse and worse. . should i be worried? if i did miscarry will my body pass the remaining tissue on it's own?\n\n### Assistant: hi if your still worried just go see your doctor he/she mat suggest you have a d&c its just like having decoke of the womb. but please see your doctor just to be on the safe side. good luck
