Period after birth

VMR

How soon can you get your period after birth?

I had my son aug 20, so it’s almost been 5 weeks.

I’m asking because I was at the point of really light spotting of old blood and then had my PP checkup, and after he checked me I started bleeding red blood again. It’s staying red and it’s slowly getting to be more.

So idk if it’s just blood that was ‘trapped’ or if I’m starting my period
