16 AND POSSIBLY PREGO???

Sarah • 💍
I'm 16 almost 17 and I got off my birth control Around a month ago bc I thought I was getting my period while starting a new pack [ usually do 3 month periods ] Its been and while since I had my period. My boyfriend and I  had sex multiple times without condoms were just doing a "pull out" method. I think I might be pregnant. he says not to worry but we've had sex around 10 times this month. I thought I was gonna get my period a month ago. still nothing, should I be worried?
