Bleeding during first trimester

Hi all, I’m currently in my first trimester (around week 6)..experienced bleeding with clots and went to KKH urgent O&G yesterday..doc said mine is a threatened miscarriage and prescribed progesterone over 2 weeks..they did scanning and could see baby and heartbeat..did not have any bleeding for the next 24 hours until now (the next day) where I felt a gush of blood again (fresh blood with clots)..just wondering if this is normal even after taking progesterone? How long does it usually take for the bleeding to stop? Am very worried and paranoid :(
