not a norm cycle this month

I have a 33 day cycle but around day 10 I got a lot of ewcm and then around day 16 I have been getting cramps backaches like af is coming it wouldn't surprise me if it did because af has been on que every month for awhile well except my last af which it started on the right day it just only lasted 2 days so I'm guessing that's why I'm probably a little out of sync af is due on the 3rd of June so I might get it a couple of days earlier than the norm😊
