Missed period

Hello! So.. I missed my period this month. I am on birth control and I’m pretty good about taking it. (Other than the occasional missed pill and not taking it at the exact same time every night. I usually take it within a range from 11-4 am. But I missed my period this month and just started a new pack of my bc pills last night. Should I take a pregnancy test? Or do I need to wait longer? Recommendations? Help?
