Uterine Prolapse

Hello mummies! I had my 1st Csect for my 3rd child a month ago and am still having major constipation. Even after eating loads of fruits, vegetables & water. I even take lactulose and oats daily. Still no change. So when I strain, I can feel something bulging out from my v! Read up and realised that im hvg uterine prolapse. Anyone that had the same problem? Should i go back to my gynae or just go to a gp? What/how is the treatment? ?
