Hi, I Am From The UK. I Had A Hysterectomy

Hi, I am from the UK. I had a Hysterectomy on Monday 20th April, was supposed to be a total but the surgeon couldn't remove my Cervix as it was stuck in scar tissue from previous c sections and he said it would of rendered me incontinent. All my gynae bits were apparently stuck to the scarring including one of my Ovaries. He said it was a mess in there and the surgery made him sweat alot. I am wondering how long the swelling takes to go down as I quite liked my flat stomach
Thanks
