PLS READ IM DESPO AM I PREG

I've been taking the pill consistently the past month, except for the third-last and second-last day of taking it, where I missed my alarm. I had sex (without condom) with my boyfriend on the last day of the pill and he came inside me. I would usually get my period a day after I stop, but now it's been three days since I've stopped. And still nothing. What should I do?
