What Causes Spotting Of Brown Discharge While Having IUD Inserted?

hello



i am 19 years old and i am on birth control with the IUD(COPPER).

i didn't get my period on february but i just had my period on march.

i am concern because i am having spottingsbut they dont look like red blood color they sort of look redish/brownish.

Just in case for more info i have a history with the IUD(COPPER)...i got pregnant while i was with this birth control but had an abortion..doctors found that the IUD was properly installed.

If you could please help me and tell me if this is something i should rush to my clinic?

Thank You!!
