Enne: IUS. Yup, that's the other alternative if we don't opt for ligation. IUS is for 5yrs.. I was thinking, during this 5 yrs, if we want to have a baby, we have to go remove the IUS, which given how lazy we are is quite unlikely given we already have 3. So after 5 yrs, we may then do ligation, then it's like going one big round lor.. *sigh*.. Nevermind... I'm still considering, and letting my hubby think over.. Maybe he'll change his mind..
