Irregular Cycle TW* Blood

HH

This month I tracked my cycle, finished my period and it was looking great on the lead up to my fertile window. We baby danced for three days up to my most predicted most fertile day however I woke up to a heavy bleed which lasted three days. I’m so confused, has my period come early? Do I start from scratch with my cycle dates or do you think I’ll have another period in 5 days and continue to test on glows predicted fertile window? Any recommendations or shared personal experience stories would be much appreciated 🤍.
