2 weeks post The pill

Is it possible to get pregnant 2 weeks after you stop taking the pill?.. My BF asked me to stop taking so I did and we’ve had ridiculous amounts of sex since then and I’m due to start my period today.. I’ve been having random dull cramping for the past week not like pre period cramps but I took two tests and they were negative.. it’s now been a month since I’ve taken any BC.. 😬
