"i have used this pill twice. my boyfriend and i have been havjng unprotected sex for about 2 yrs. we usually use condoms and sometimes we do it without one. the first time i took the pill we weren&#039;t sure if he had came in me. i took it the next morning and had no symptoms at all. got my period on time. this is the second time i take plan b. i took it after 30 mins of having sex.  and a week later im getting the worst cramps ever. i hope it works because i&#039;m stressing out."
