... unprotected sex with my bf the following Friday night around 11 pm. I know you're supposed to wait 7 days before it starts working but I only waited 6 and a few hours. Is the amount of time I waited long enough or could I be pregnant? Please help, because if there's a chance I could be pregnant I still have time to take a plan B! Also note that he didn't cum inside me but we did it twice in a row, with him sticking it back inside me minutes after wiping off the cum from before.
