"so me and my boyfriend had sex, he thinks he ejaculated inside me so i took the plan b right away. the symptoms are terrible. i had lower abdominal pain, fatigue, dizziness nausea, i was so tired all i wanted to do was sleep. today is february 11 2017 just one day after i took the pill. it&#039;s a great backup but to be honest i will never take it again. i experienced all of the symptoms at the same time. not a great feeling."
