Menstrual bleeding lasting too long?

I will schedule a gynecologist next week I just want to hear if anyone else went through this

After birth I bleed for like 5 and a half weeks, and I got my first cycle 6 weeks pp and it lasted like 10 days🙄 25 days later I got my cycle AGAIN but this time it’s going on for 15 day. It’s not heavy, but it’s still pink and going on for so long and when it’s stops I am about to bleed again and that annoys me so much

Is this normal?? Have anyone went through this and what was the problem?
