I had a doubt whether ur surgery was done with an incision (cut) over abdomen or Through Vagina.
Anyhow it doesnt matter which way surgery was done , YOu have to take rest atleast for 1 month and after that you can try lifting objects which are not heavy from ground and see whther pain is there or not. if yes it means u have to wait 1 or 2 more weeks to the heavylifting.
Remember post any abdominal surgery
if u dont take proper rest u will develop herniatio due to weakened muscle of abdomen which does not imply for a vaginal hysterectimy where u have to look for pain alone
