First period after baby

Hannah

So I had my baby boy on December first and exclusively breastfed him until the middle of April. On June 18th (last Monday) I woke up bleeding with my first period after giving birth via csection. It’s now Saturday the 23rd and it’s showing no signs of slowing down. This is probably the heaviest period I’ve ever had and I’m still having bad cramps. Before I got pregnant my periods were very regular and only lasted 5 days each time and on the 5th day I barely bled. I’m so worried it’s gonna last a really long time and my periods will be this way from now on. Is this heavy period that’s lasting a long time normal?
