Period log question

Molly • IVF/ICSI 2015 👶 Jan 2016 FET 2020 👶April 2021

My period was due to start yesterday (cd28)according to my period log estimation. My period has not started yet it has me at cd2. Is there a way to change it so it knows I am still awaiting my period? Or do I just mark the day when it comes? My cycles are 27-33 days.

Thanks!
