Postpartum bleeding

I'm not sure if this is where I should post this, but I'm hoping someone can help me out.

I recently had a baby boy, about 4 months ago now, and after the regular 6-8 weeks of bleeding after birth I'm a little confused.

I'm exclusively breastfeeding and I've heard that can play a factor in this... But what I'm curious about is...

Is it normal to have a period every other week after having a baby?

Pretty much I bleed for a week and then am off for a week.

I have very mild symptoms if any. Maybe some cramping but very light. I just bleed and then stop. And then a week later I start up again.

Anyone else have this happen to them?

I'm not super concerned because I haven't had any pain, no major clots, and no fatigue whatsoever.

It's just kind of annoying haha.

Any thoughts?
