birth control question!

so today i start my birth control (ive already been on bc) but this is different because its the extended kind. it says to start on sunday but the 7 days of my inactive pills on my last bc just ended today which is monday (11/14) so can i just skip the sunday pill in the packet and take mondays? im not really sure, i dont want to screw myself up. if i take sunday ill just always be a day behind on the packet? im confused!😣😣😣😣 thanks for helping me!
