I Have Not Had A Bowel Movement In Days I

I have not had a bowel movement in days I have taken 16oz magnesium citrate ,fleets enema, 4 biscodyl suppositories, 4 Colace tabs and have taken 14 oz of miralax and have increased my fluid intake Urgent care referred me to the local emergency room. Xray of abdomen showed air pockets. doctor said after digital exam there wasn't any stool in my rectum. I was sent home with the advice of drinking more magnesium citrate So now I am into my second week and still no BM. What in the heck do I do?
