Postpartum bleeding

I'm 3 weeks postpartum. I didn't tear but I'm bleeding more now. At first it was like a light period with some blood clots & then it got really light just spotting & I would only bleed once or twice a day. Now it's like a normal period. Am I on my period now? With my son I bled a lot for about 4 to 5 weeks then it stopped for a week & then I started bleeding again which I'm guessing it was my period. So I'm just wondering for any of you that didn't tear. When did you all stop bleeding? When did you start your period?
