YASMIN pill - how does it work?

Hi guys! I just got prescribed the YASMIN pill from a doctor, who didn’t really explain much. This is my very first time starting a pill. He told me that I should start taking the pill when I’m on my period, but I finished that about 2-3 days ago. I told him this and he said it’s okay, it’s still good to start it now. I got my period Friday 3rd of May and finished around Thursday the 9th. Can I start today?

He told me to take the Saturday pill for today and follow the arrows.

Im hoping someone can help! I really want to start ASAP! Thanks x
