bleeding sorry if tmi

Angie • Pregnant with a baby girl!! 💖
I'm confused this is my second period since my recent miscarriage (I've had 3)  my period was two  days long (normal for me) and ended the 28th. ever since I've been spotting! For 4 days now and I never spot ever. Not only that but it's  little spotting and I've been having small blood clots come out with no extra blood just the clotting. My period ended with brown blood and is now back to pink/red spotting and now I'm having thick brown discharge?! Which has only happened when I miscarried and I am not pregnant now. What could be going on?
