When is the first day of my cycle?

Hi, I am on the rigevidon pill which is 3 weeks on and 1 week off. I am just trying to work out when the first day of my cycle is to help improve my gym/exercise routine. Would it be the first day of my off week? The first day I start a new pack? Or the first day of my withdrawl bleed (which is usually half way through my off week) any info would be much appreciated. Thanks

I'm pretty sure it's the first day you don't take a pill :)
