7 weeks pp bleeding again

ty

I had my baby 7 weeks ago. I bled heavy for the first 2 weeks but then continued to bleed not so heavy up until 5 weeks. The bleeding stopped but I still had lochia. Just today I started bleeding again, not heavy, but it’s almost bright red. Is this my period already?!

Mind you i’m breastfeeding everyday and I just started a low hormone birth control this passed Monday.
