Any help would be appreciate

Hi ladies. So I am on the Xulane patch and have been on it since August 2018. My bf and I are sexually active and we ALWAYS use a condom every single time and he never finishes inside me. I take off my patch on Sundays and get my period on Tuesday or Wednesday. It is now Wednesday (9:28am) and no sign of my period. Should I be worried? Do you recommend I take a pregnancy test? Im a little nervous right now.
