Can someone tell me if this is normal?

*TW: BLOOD*

I am 4 weeks pp, I have been bleeding but not too bad, for this 4 weeks. A few days ago, it was turning into brown blood; and then it stopped for like a day and then it started back up again but it’s bright blood and a lot. This is the most I’ve bleed this whole postpartum. Do you think it’s my period? I have a history of really heavy periods before I was pregnant.. I’m just worried. I need to know I’m not the only one that has experienced this.

This pic is after I sat on the toilet for like 20 minutes.. it was so full of blood and looked worse in person
