Your Question: "My Boyfriend Did Not Penetrate Me At All

Your question: "My boyfriend did not penetrate me at all and did not climax, but I was still worried about getting pregnant because of pre-ejaculation. I took the Plan B pill approximately 17 hours afterwards. I have not experienced any vomiting, but I am extremely fatigued and have lost my appetite and it has been 9 hours since ingestion. I was wondering how likely pregnancy is in this case and how long will my side effects last?
