Bleeding afterbirth

Hello po. Ask ko lang if may nakaexperience rin ng naexp ko. Continuous kasi bleeding ko till 1 month and a week. Then nagstop ng 1 week then now nagbbleed ulit ako and Im thinking na mens na to. Pero yung dugo ko is di nmn buo buo so diko sure if eto na 1st mens ko after giving birth. Is this even normal? I am pure breastfeeding.
