Pregancy scare!

ri

Hi!’ Everyone plz reply- okay so In the beginning of this month i missed one of my pills... (it was towards the end of my period, taking the sugar pills) then the next morning i had sex and let my Bf cum in me. But later that night i took two pills and catch up... I’m supposed to start my period in the next two/three days and I’m kinda freaking out. Anyone think their could be a chance I’m pregnant ? I think I’m overreacting but i am praying I’m not pregnant because I’m 18... help!
