Question!

So I have been on birth control since I was in 6th grade to regulate my period now it’s like I don’t even have a period if I don’t take my birth control, so I took a full pack and started my period on June 20th my period lasted 4 days. I waited until the next Sunday and started my pills I took them for 3 days, then me and my boyfriend decided we want to get pregnant. I took my pill Monday, Tuesday and Wednesday. We have had sex Wednesday, Thursday, Saturday and today. By the app this is suppose to be my fertile week so if I have had sex for 3 days with no pill and continue to not take my pill and keep having sex until my fertile days are over is there anyway I could get pregnant? Will the pill be out of my system enough to get pregnant?
