Problems and pain after abdominal hysterectomy?

i had an abdominal hysterectomy 3 weaks ago,i had my uterus and cervix removed-my bladder ended up being cut as well (due to scar tissues that formed my uterus and bladder together) i still get some pretty annoying pain and i have a hard time to do #2 and it hurts my stomach area and on the sides of my pelvic/abdoman area is this normal- how long before the pain completely goes away? if u had your bladder damaged during a hysterectomy how long did it take to get back to normal bladder function and pain free free when u have to hold your pee. please help especially if u had a hysterectomy.
