clots but no actual blood?? TMI

joy

i had an iud inserted about 3 months ago and the insertion recovery went awful and i ended up basically having a 4 week period. everything is ok now but i just had my first actual period since the initial bleeding stopped. my blood had been almost like normal discharge but just brown and these brown clots. it went for abt 3 days then stopped. then the brown discharge came back on and off. wtf is this pls????
