Hi avyi
Welcome ☺️
I had a hyster 3years ago, still go my ovaries and was told my surgeon that 12weeks is minimum for anyone to return to work, ( you don't say what your job is)
You can phone or go into your practice and request an extension on your sick leave
You've had major surgery, and some people can bounce back quicker than others, and you're out of your routine
Also mention to your go phased return to your work
