Can you get your period 4-5 weeks post partum?

A❤️C

I'll be 5 weeks postpartum on Sunday and I had almost stopped bleeding. Just needed a panty liner daily for very light brown discharge. Today i woke up with a lot of dark brown discharge and now I'm bleeding lightly. This used to happen at the start of my periods. Am I just still bleeding ? Or is this my period ?

If it's my period can I use tampons? So sick of pads.
