Well I've spoken to 3 people now, 1 of whom has experienced this and gone on to have a healthy clutch... the general feeling seems to be that given the time since the prolapse, the muscles should have healed and she shouldn't have any problems!!
I'm sure that I'll still be like a cat on a hot tin roof, but I'd like to give her a try - first signs of trouble though and she will be off to the vet and kept as a pet only for the rest of her days!!
Thanks again everyone!!
