How many times does a tubal ligation fail?
Very few, in actual fact. However, even if the tubal ligation itself is perfect, pregnancy may occur in approximately 1 out of 1,000 cases. This may happen during the months immediately following the ligation or even several years later. If you have a tubal ligation and your period is late or there is abnormal bleeding, you should have a pregnancy test to make sure that you are not pregnant.
