I Had Diarhea On The 18and 19 And Did Not

I had diarhea on the 18and 19 and did not have a BM until this morning. I took Miralax last night and have been taking Benefiber in the morning (per my doctor's orders. I Haven't been able to reach the office due to having no cell service where we are) the stools are greenish in color. I went several days with only liquids or items recommended. I felt better and increased my intake, but now have cramping again. Should Imcontinue with Miralax and a mild diet?
