period/bleeding after stillborn

An
Hi ladies! My daughter was stillborn at 21 weeks on November 20th. I had some heavy bleeding for a couple days then spotting for about a week and then very light brown spotting for about 2 weeks. Then I got a gush of brownish/pinkish blood and had more brown spotting for a few days and now I'm cramping and it kind of looks like a normal period? Is that normal? I don't have any abdomen pain besides my cramps, no fever, I don't feel sick, is this my period returning? The first time I miscarried was early on and I had a D&C, and had bleeding for a couple days then didn't get my period until 6ish weeks later. Just looking for some advice please!
