First period pp

Okay so I got my first period since having my daughter and I have a few questions being a ftm and all. I’m legit bleeding so dang bad! I can feel oh just running out of me like a waterfall. TMI I know ☹️ but is this normal? I have my 6 week pp visit this morning but I’m gonna have to reschedule it cause I’m so uncomfortable. Is this normal? Before i had her my periods were bad anyways. Just wanting to see if this has happened to anyone else
