periods or lochia coming back?

This is going to be a bit tmi sorry!
So here it goes, I gave birth to my baby girl 6 weeks ago. I bled for about 4 weeks and it slowly stopped. My mucus was still a bit colored but coming back to normal. And then since yesterday I have a little blood as in pinkish when I wipe and a small stain on my undies. I felt my lower abdomen tightening a few times that could resemble tiny period cramps but very very light. Nothing really worrisome but
Baby is exclusively breastfed so I was really not expecting anything close to a period anytime soon but it would be very strange for it to be lochies again this late?
