Bleeding

Hello, I am almost 7 months PP, I haven’t had a period since I had my baby, which I am also breastfeeding, I did bleed almost 2 weeks ago for the first time, and I assumed I was starting my period since it lasted 3 days. But today I bled, which looked brownish and maybe I thought old blood then I started bleeding again which was very red and thick. Is that normal?!
