I had a vaginal hysterectomy, also for prolapse, with some bladder suspension done at the same time. I did not have the additional complications of a true cystocele or rectocele though. I had company in town and was feeling well enough to cook for them and go out to dinner, that sort of thing at 3 weeks post surgery.
I could not have attended 3 births prior to the 6 week mark. I would be very very cautious about expecting that of yourself. This is a major surgery, and very painful to recover from. Mine was uncomplicated, and was still the worst pain, and the most exhausted, I have ever been. And I had three non medicated, 2 with good size repairs, hospital births. The surgery took longer and was more difficult a recovery by far.
You may be able to attend one, or more if they actually went to or past the dates you had listed, but you would still want to be careful.
BUT as a side note, as much as I am against the medical world as a whole, and removal of body parts, the choice to have that surgery done was very difficult and worth every minute. I am now a happy person no longer living in constant misery from all my gynocological issues.
Hope it goes well and everything works out for you!
