Can I have unprotected sex an hour after taking the last bc pill?

Hi so I ordered some BC pills from nurx and they’ll be here either Thursday or Friday... and I’m planning on taking it as soon as I get it to be ready for next Friday... so let’s say they get here Friday and I take them at 1:00 pm... and the Friday after will be the last day of taking them to be protected from pregnancy so let’s say I take it this Friday at 1pm and take the last one next Friday at 1pm....and I have sex like at 9pm will I be protected or do I have to wait another day?? Does this make sense? Ahah
