"my boyfriend and i had a mistake we usually use my cycle awareness and pull out method as birth control. it was successful for 6 months. we had a mistake one night and i knew i was ovulating so i went to the dr the next day and took the plan b within 24-30 hours after the mistake. well 2 weeks later i started getting my usual period symptoms; sore breast, tired, hungry, irritable, bloated. but this time the bleeding never came. i&#039;m now 8 weeks pregnant. the doctor said it&#039;s rare only 5% but it can happen. so please be careful! i&#039;ve had other experiences with plan b that were positive and it worked but i guess god had a different plan this time."
