Period after baby

How long does it take for your period to come back after birth? I’m 10days postpartum but I’ve stopped bleeding really I’m only spotting. Not enough to fill a pad at all so i haven’t been putting them on and it fills the panty liner just a bit not a lot. I usually have my regular periods for 3 days. I bled for a week after birth. I know my body is getting back to regular though but how long has it tooken any other moms to get their regular cycle?
