so a little more than a week ago i had sex with my boyfriend it was a fun day and more than once . I'm on birth control and it was the first time we had sex without a condom , his pull out game was strong everytime so i took the plan b and then the next day we had sex again just like the day before and i took another plan b ... so that was a week ago my period was supposed to start yesterday. i just want to know if it could be the plan b ? I'm a little bit nervous that it could be that I'm pregnant but i don't think it could be that ... what do you think ?
