Bleeding 5 Months After Abortion

I got my abortion on February 13th, it is now June 11th and the bleeding has not stopped.
for a short period of time in March it had slowed and would only maybe start once a week. But recently (in April) I have had a constant and generally heavy flow everyday, without pattern.

I sometimes pass large clots that are dark red in colour (looks like my period)
and I sometimes pass clots that are bright red in colour (fresh blood)

I am experiencing no pain, no nausea, but I am experiencing anemia.

Any ideas? or has anyone had this same experience?
Any help on what this could be would be great, Im growing very, very worried.
