I started mine at 7 weeks post partum but I think it may have been because I started taking the mini pill around that time

I got my period after pp bleeding

I bled for 6 weeks after giving birth then 2 weeks after, I'm 4 months postpartum and I haven't gotten another period since they say it's normal since we exclusively breastfeeding to not have periods or if we do its not going to be normal like it will be once in a blue moon.
