Bowel Movement Fear

Ha
I am literally terrified to poop!!! I gave birth on Friday 1-27 (3 days ago). I had diarrhea on tuesday and Wednesday, haven't gone to bathroom since. I was ripped open by baby girls shoulder and have stitches and second degree lacerations requiring moderate repair. I am seriously terrified to go poop. How bad does it hurt? Doctor said I can drink a laxative but I don't want to go bc I heard the pain is really bad.
