period after pregnancy?

So I think maybe starting my first period 😩😩 I thought and was hoping I would go longer since I am ebf. I'm 9 weeks pp and barely stopped bleeding from my c section at 6 weeks pp (4-6 weeks pp was spotting) and tmi but just went to the restroom and there was a dab of blood in my underwear and very faint blood on the tissue! I have no cramps or anything else! Is It period or maybe some old blood!?
