"i am only a teenager very young. only being the end of grade 10. and i had unexpected and unfortunately unprotected sex with my boyfriend on friday around 8pm. he pulled out before finishing although i was and am terrified about precum. he told me about plan b and offered to pay for it. i took it at approximately 10am the following saturday. i experienced headache and fatigue. i took a nap and the symptoms went away. my expected period is next week an i just want to say thank you to everyone writing these reviews because you&#039;ve calmed me down so much."
