What Causes Blood Stained Cervical Mucus Discharge After Inserting Copper T?

Hi, may I answer your health queries right now ? Please type your query here...hello sir,i am a mother of two children,i was inserted copper t multiload early this year. I have not had any serious complains till then the only thing that worries me is that sometimes i experience a blood stained cervical mucous even when i am not having my period,but they are not heavy as such. Is it normal? Thank you,mercy.
