Hi there, I'm 17 and I've been on the contraceptive pill for nearly three years. I engaged in unprotected sex (stupid I know) with my boyfriend after only having a week of the active pills as I accidentally missed two whilst on vacation. I'm currently going through my final school exams and am trying to differentiate between whether I may be pregnant or just stressed. I've been getting pains much like menstrual cramps and have had horrible back pain since the incident, I apologise if this question seems bothersome, I would just like to know, thank you for any help or advice you can give me :)
