Period or continuous postpartum bleeding?

5 weeks ago i gave birth to my daughter, and i had the typical post-partum bleeding for about 2 or 3 weeks. it started tapering off and went from reddish-brown to just a light pink in the 3rd week. there was only a little bit of discharge that was sometimes light pink or brownish.

well now i'm 5 weeks post-partum and i just started having bright red bleeding again. I caught it soon enough while I used the restroom before it got heavy. It seems like a period since I have slight cramps, and felt nauseous the past 2 days.

I also pumped, and formula fed the first 3 weeks since DD couldn't latch. I've been breastfeeding and supplementing since she learned how to. I don't see my dr for my check up until next week either. 😭
