Does previous use of birth control pills reduce their effectiveness?

Good morning, I have a question about whether my taking of tablets at the current blister is "correct" and the protection has been maintained. This month I had several situations where I could not take the tablet at my fixed time, hence I also took it earlier (apparently taking the earlier tablet remains effective). I took 12 blister tablets an hour earlier and took the tablet the other day at my fixed time. Then I took 18 tablets from the blister 10min earlier (also the other day I took a fixed time), 24 tablets I took 35 minutes earlier (and also took at a fixed time the other day) and today 26 tablets (2 placebo) was taken 20 minutes earlier. On other days I used at a fixed time. Could my recent use of the tablets have reduced efficacy and not fully maintained protection? Tomorrow I should get a scheduled withdrawal bleeding. At 4 times where I took the tablet earlier (max up to an hour) is there a risk of pregnancy?
