Hello I Was On Birth Control And Stopped Until I

Hello I was on birth control and stopped until I got regular periods (about 6 months)my last one being 12/27/2016. I had unprotected sex the 7th of this January but didn't think and took birth control the next Sunday. My boyfriend wants me to take a pregnancy test my period would usually come the last Tuesday of the month or Tomorrow . Do i test tomorrow or next week when the birth control pack ends and it "starts" my period?
Thank you
