Question... miscarriage / period

Hi all. first time posting here although I have been using this app for a year now.

5 weeks ago I had a miscarriage (was 9wks pregnant) since then I haven’t stopped bleeding (only light bleeding) now 9 days ago I started bleeding which means my period is back to normal.

My question is it is normal that period last longer than 4 days after miscarriage? I am fed up bow 😤

Thanks in advance 😘
