Weird period!! Help

Okay so I was suppose to start my period on the 16th!!! Didn’t start. I ended up starting on the 17th very light! Only when I wiped. Then today the 18th. I usually bleed a little heavier but this isn’t even filling up my ulta tampons. I typically have to wear ulta tampons to give you a picture of my flow!! I’m not sure if this has happened to anyone? And what was your end result
