welcome to hcm
are you getting pain along with the bleeding?
generally after copper T insertion a few periods are heavy and painful. it may be due to local reaction. but with time it will get better in a few months once your body gets more used to the Copper T .
if you are having pain then pain killers like mefenamic acid
if you are getting heavy bleeding then consult your gynecologist and try to take cu t out and go for other contraceptives.
if you have the problem of getting heavy blleding after delivery and not related to cupper t then other causes to be ruled out
generally its normal after child birth called lochia
. It will stop by the time you go for your six-week postpartum .
wish you a good day and take care
