For the last couple of months a few times a week I will notice poop stains on underwear. Sometimes I have had flatulence and sometimes not. Evidently some bowel movement leaks out without my knowledge at times. Is this a sign of cance in th=at are of body? Should I be concerned? I was taking stool softener every morning but have stopped and the problem does happen less frequently now--about once a week. ThANKS FOR YOUR ADVICE. I see on the page where payment is required it says this is a monthly payment---does this mean I pay every month or just this once?
