Hello
Thanks for your query.
The bleeding is due to the infection of the vagina and
uterus.
This is called
vaginitis and
endometritis.
the infection presents as severe bleeding and foul smelling discharge and odour.
The culprit is the IUD which has been removed already.
The remaining symptoms will settle down once the antibiotic course is completed.
once the infection subsides, bleeding too will settle down.
Take care.
