I have not had a bm since wednesday as of yesterday had no bowel sounds have taken lactulose and miralax (polyethylene glycol) with no relief I am no nauseous what can I do?

Constipation. If you have the urge to have a bm but can't, try working from below using dulcolax rectal suppository and/or a gentle low enema like fleets. If you have abdominal distension, severe cramps or vomiting, you will have to be examined by your physician who sometimes has to disimpact you by breaking up and removing impacted stool or prescribing a higher enema.
