I Was Scheduled For A Colonoscopy And Endoscopy Today. I

I was scheduled for a colonoscopy and endoscopy today. I was prescribed Moviprep as the bowel prep. I carried out a pregnancy test on Thursday which was negative and complete the bowel prep schedule on Thursday. On arrival for my appointment and as part of the admission a pregnancy test was carried out with a positive result. It is believed I could be 3-4 weeks pregnant.... Should I be concerned regarding the laxatives? The treatment was postponed and the sedative wasn't administered but there is very limited info on Moviprep and pregnancy and I am extremely worried.
