Post partum period

I'll be 8 months PP on Aug 6th. I got my first PP period June 27th it was light, normal, lasted a week nbd. BUT then I had spotting on and off from July 17th- 20th I noticed when I had cramps is when I'd go wipe and see a little blood. Now I've had horrible cramps for the last few days.

Is this normal PP period stuff? I'm still breastfeeding. And idk if it matters... but I did get both doses of Moderna. And my husband and I have used protection every time, and he's also gotten a vasectomy.
