How long after childbirth did it take you to get your period ?

I’m 4 weeks 3 days postpartum and I think I got my period, although it seems a little soon especially since I’m breastfeeding. My postpartum bleeding lightened up 2 weeks ago and had pretty much stopped, it was also thick and light pink at the end. Starting yesterday I had thin red blood that is heavier today and I had some cramps yesterday, also which I haven’t had for the last two weeks. I really think it’s my period. Did anyone else breastfeeding start this early?
