using bc pill

so, i started taking the birth control pill the first day of my period which was the 24th of august this year. so just a week ago. i ended my period just a day ago. so tonight i had sex without a condom and i had been consistent with the pill for 7 days straight plus todays which is 8 pills. i did some research and it says tht once u start the pill the first day of your period, ur protected alrdy and i had also done a whole week taking the pill.

am i okay? should i have waited longer? are the chances of me getting pregnant high or pretty low? i mean i know tht the pill isnt 100% effective but its safer than a condom.
