Help! Is this normal?

NNEJ • 35 Yr old Mother of 2 girls and 2 boys 🥰💕💙

Postpartum period came sept 1-20 (very long!) I just started bleeding again yesterday and just now passed a HUGE blood clot. I felt it come out and I moved it around with a q tip and noticed it was very thick. Is this normal? My cramps have been sooo bad since yesterday and I never have bad periods like this. I did get the depo shot right after my postpartum period last month was over. I’m freaking out!
