Bea,
Can't talk from personal experience. But my mother had a prolapse repair. (she used say it felt like carrying a brick around down there). She has never looked back and often wonders why she didn't seek help earlier. I think you would need to give serious consideration re more bubs however i'm sure if you decided to procede with surgery the surgoen would have that disussion with you. The gyno that did my mothers repair speaks very positive about the surgery and feels it is sad that so many women suffer in silence.
Not sure if the above helps but all the best and take good care of yourself.
