Cycle chaos!

Rayn
Hi everyone!! 
I have recently started using glow.. and to my frustration noticed that my period is 23 days and I'm on about 3/4 days. I was on a week ago, now I'm due my period in two weeks! It's really frustrating and emotionally up-down. I was wondering if anyone had this and how to manage emotions etc? 
Thank you in advance! Have a love evening!
