sometimes i don't go for 2 weeks. when i do go, it isn't hard or small as it is with usual constipation. i went to the doctor and she prescribed miralax and stool softeners for me. i've been taking them for a week and it hasn't made any difference except given me cramps. also when i was at the doctor, she had x-rays taken, and the only thing the report said was that i had medium to large stool in my colon. i eat very healthy, drink plenty of water, exercise daily for at least an hour, and i'm 15. can this be something serious?
