I NEED HELP

me & my boyfriend had unprotected sex a week ago from today (last tuesday) & he came in me 3 times but i took the pill the next day in the afternoon. i was supposed to start my period the day before (monday) so it was already a day late. but i still haven’t gotten it & it’s been 8 days & i’ve been spotting for about 2 days. is there a possibility i could be pregnant or should i wait another 2 3 weeks to take a test?
