you bleed from the lining that is shed from your uterus. having a tubal ligation only prevents pregnancy. it does not prevent ovulation or the cyclic changes that create your monthly period. you will continue to have periods just like before (or there could be some spotting changes in your cycle) until you go through menopause. discuss this with your gynecologist -- someone who knows your medical history.
why if a woman has her tubes tied does she still get a period? normal to be worse & linger longer afterwards? . my periods seem to spot 3-4 days after the normal 7 days. i've had 2 c-sections & after 2nd had tubes tied.
