Period after postpartum

I had my first period after postpartum the 7th of February, it lasted till the 15th . That was like a week ago , and on Friday I started to spot and getting cramp like if I was gonna start my period AGAIN , I didn’t bleed enough to fill up a pad , I just could see blood whenever I whipe myself after using the restroom , Saturday I bled a little bit more then just spotting and then it stop , and since yesterday I didn’t spotted at all , is it totally normal ? I’m not on birth control, and I know I’m not pregnant . I just want to know if is normal ? I’ll appreciate it
