Wala naman side effect ang tubal ligation, or perhaps it depends sa bawat mommies. Under anesthesia ka naman during the procedure.
If fully decided na kayo at ayaw na magkababy talaga you can push this method, because pills has a lot of side effects especially long term mo siyang gagamitin to avoid being pregnant again. If payag naman si hubby na siya magcondom okay din un. Talk to your OB regarding it also. :)
