I had sex for the first time jan 25 and i was supposed to start my period feb 7, i had sex again on feb 9th and the condom broke when he was pulling out, he was stressing out all weekend and i did my best not to stress but i still haven't started my period and i took the plan B pill on the 11th. im usually never right on time with my period but ive never been this late, im starting to stress! im not sure if my body if just not used to sex yet or should i be worried that the plan B didnt work and im pregnant!
