Question about AF

[JASMAK]

Hey all. Haven't really been around these boards anymore, but have a question, and without going to my door-knob doctor, was hoping to get some insight here. I had a baby 5 months ago, I am 36 next month, and I had my first AF since giving birth 2 weeks and a smidge ago. Well, yesterday, I got a very light period??? again!! I would say it's more than spotting as I had to wear a tampon, but here I am day 2 with a light period...about 16 days past my other period? What's up with that? Is that normal. This is my third baby and so I don't know if it's hormonal...but, I have never had that happen before.
