hi there, bleeding for 13 days post miscarraige with fishy discharge does not sound normal and you need to be examined. Get an ultrasound
done to rule out retained products or abnormal decedual reaction. If there are any positive findings you need to go for a D&C and get the uterus
cleared of any recidual effects of pregnacy ,do go and get a second opinion
and get treatment accordingly.Your fever and drowsiness
could be due to infection and it could turn dangerous if neglected. Take care.
