Hi all-- spotting questions-description may be TMI

Hi all. Tmi description warning 
This is the fourth day of brown spotting with stringy or just a couple clots of discharge. Very few and light cramps with no other period symptoms. 
What could be going on here?
Background info- I stopped BC pills on 5/1, had normal bleed from that from 5/4 to 5/8, and no bleeding since. 
Thanks for any opinions or thoughts
