Help !

Two days ago I noticed pink discharge, then a day went by and I noticed it turned brown . Straight to brown . Now I have these clots with very little brown whatever it is. I’m not sure if it’s my period but I’m not understanding why I’m seeing clots with no period !!!! My depo shot finished 3 weeks ago and now this 🙃😐 on depo I bled for almost 4 weeks non stop ; I thought the bleeding would stop cause the depo is over 😐 helppppp
