First period after baby

Anyone else having a really heavy period after the baby? I'm usually one say light two heavy and then usually lightens up and stops in 4-5 days. I'm on day 4 now and it's still really heavy! Ob said its normal but should worry if it lasts longer than 10 days...I hope it will end soon! I'm 5 weeks pp and feel like I'll be bleeding forever! Lol
