Pregnant with IUCD

I'm currently 9w pregnant and still have my iucd inside.. somehow I started to bleed since last Wednesday. (Exactly the same date as the date that Im suppose to get my menstrual period). The colour is brownish and smell like regular menstrual period.I already refered to the General Hospital and taking the medicine they gave me. However the blood is still there until today...anyone have the same experience like me? What should I do?
