Has a 6-hour delay in taking 9 Slinda tablets from the package reduced protection against pregnancy?

Has a 6-hour delay in taking 9 Slinda tablets from the package reduced protection against pregnancy? I would add that I have been using Slida for 5 months now. Of course, the next 7 days to be sure I will still apply additional protection, but I wonder, because 7 days before the delay in taking the tablet I induded - is there a risk of getting pregnant? Thank you very much in advance for your reply.
