Bleeding 4 weeks PP please advise!

Sarah

For a while now I’ve been having very light pink mostly light brown discharge/bleeding and not every day. I just hit 4 weeks PP yesterday (Saturday) and today I’m having bright red bleeding. No clots and not saturating a pad or anything like that, but wasn’t sure if it’s normal. Also I’m exclusively breastfeeding. Anyone else had this? Is it normal? Thank you!!
