For the last three months I've had a bowel movement but when I go it always come out in pellets or marbles. I took dulcolax pills at bedtime last week so I went a lot the next day. So this week after 4 days of not going I took it again and it didn't do nothing for me so my dr told me to take colace and I'm going to see if it works because now I'm on day 6 and nothing seems to work.
