Does anyone else’s period hop around a lot?

Hey guys so like I have been having trouble tracking my cycle and it’s getting annoying. Usually it happens in the early AM and that is the only constant thing.

I had a period from December 4th to 12th

Then January 15th to 22nd

Then March 17th to 25th

Then May 5th to 13th

And now I’m getting mine now (June 11th)

I really don’t know what to do so like do any of you guys have any hopping periods and ways you can track them or is there like a medical reason for it?

Edit: it also hops at times as well whenever I’m physically active.

Thanks a bunchies!💙
