How does the blister pack work?

Hi! So I've been taking the pill for almost two weeks and I'm starting to wonder about the placebo week because I don't fully understand. I started on Wednesday in the blue area (starting area) and from what I've read, all the pink hormone pills need to be taken before I start the placebo week but the arrows are directing me to the placebo pills first and then to the 4 I haven't taken after the placebo week. My question is, do I have to take those 4 beginning ones that I didn't have at the start (so they're in the blue area) before my inactive pill week or do I just continue on to take those 4 after my placebo pills and then start the new pack on the same day I started this one and continuously do that every month? 
Thanks so much to anyone that can help me! ❤️
