Birth Control and Plan B

Jaimee • 17 and just trying to get along in this crazy world | together forever with my middle school sweetheart ❤️
Okay so i'm 17, i've been on birth control for 3 years and last night i had unprotected sex, so i took plan B fourteen hours after. My period f supposed it come in 6 days, do you think it'll come or i'll miss it due to the abundant amount of hormones now in my system? I just need help please and advice. Thank you all so much! :-)
