Heavy bleeding?

Leah • ✨Leah✨PCOS 👣🌈 Angel baby 12-13-17 👶 Arianna Kaitlin 8-24-09💜 Engaged 💍 Rainbow baby due 11-21-2020 🌈
Heavy bleeding after already having my period from the 29th to the 1st. What would cause this??? I'm not cramping or anything just bleeding very heavily with clots, and I usually don't even get clots with my regular period. My periods have been regular since I got my birth control removed at the end of May. Please help me!! :'(
