my last period was on july 28 and i was supposed start my new pack on 8/31/2011 but i was away and missed 4 days of the pill but i made up those missed pills. so i took the last pill on 8/5/2011 and decided not to take it anymore.and since then i have had unprotected sex,for the past days i been having cramps and since 8/16/11 i feel that my breast are a little sore. what do you think? dont take me wrong i am excited! but nervous at the same time. thank you for feed back
