Sterilization is a permanent procedure and it is very rare to get pregnant after it. However, if the woman does get pregnant, it's usually ectopic pregnancy which is in the fallopian tube and not the uterus. After 6 years of the procedure, it can still occur even though the sperm can't get to the egg. So can you explain how that happens, because I'm a bit confused..
But did you bother to watch?
