Hmmm supposed to prevent pregnancy but there'r still % risk of it..
Has heard 2 stories of failure to prevent.. 1st was done at pte hospital, the gynae was so kind to sponsor the whole antenatal as well as delivery.. But the 2nd case was by Kandang Kerbau Hospital.. The family had 4 , now #5. sigh.. When I shared about the 1st case to them.. They says dont't bother as Kandang Kerbau Hospital sure won't be like the pte one, so kind to sponsor..
Anyway I heard that the Kandang Kerbau Hospital charged around 1k (after subsidy) for the whole procedure..
