Super Strange Bleeding

I bled for about 5 weeks postpartum. My bleeding stopped for 3-4 days completely after it had turned whitish/yellow and then went to a medium/heavy flow bright red bleed a few days before 6 weeks postpartum. My doctor thought it was my first period even though I’m EBF. I bled for my usual 5 days of my period. It stopped 5 days ago then today started up again like a period flow bright red. I started the mini pill last Friday. I’m so confused as to what is going on.
