Should I worry?

Ik there’s a lot of these but this is my first month in the pill and I take it like I’m supposed to. I read the pamphlet and I’m covered after 7 days, yes Ik bc isn’t 100% effective. I let my bf finish in me around my 20th pill. I’m on my fifth sugar pill today and my apps say I should start today or tomorrow but I haven’t had any of the signs. Should I be worried?
