bf nutted in me and worried!!

ok so basically i had unprotected sex like about a two weeks ago and my bf said he busted in me when i was riding him! i take birth control but i’ve been spotting for about a week or maybe a lil more and i know i’m suppose to get my period next week but i’m so worried!! i usually never miss a day of taking my pills but i don’t usually take it at the same time as my doctor recommends but IM LUKE EXTREMELY SCARED IF I CAN GET PREGNANT or not
