Can 1-2 hours delay in taking Slinda weaken the contraceptive effect of the pills?

I took slinda tablets quite irregularly at 6 p.m. I often took them at 7 p.m. or even once at 8 p.m. At the start of a new blister after placebo tablets, unfortunately, I again managed to take a tablet an hour late (according to bleeding it was the second day of the cycle) and then there was intercourse Now I take pills every day at 18. But could being late earlier have a negative effect on contraception?
