Suddenly Weird period

My periods are normally really predictable. Spotting/light for 1-2 days, then heavy for 2-3, then light/spotting for last 1-2 days. They’re also in line with my eve start date. This month, not so much. Started almost 10 days late. Started somewhat normal, then after one day of light flow it seemed like it stopped. Spotting for two days, then heavy for a day, then seemed like it stopped. Been having heavy bleeding now since yesterday afternoon. Just not sure what’s going on. Not sure when to be worried since womens bodies can be weird with stress. In any case, just wanted to get that off my chest. Appreciate any feedback!
