Me and my boyfriend having some intimate moments on night of Feb 9. We touched our genitals.. though he didn't penetrated (I felt that he was touching below the hole) and ejaculated outside.(No ejaculation before that ) I was worried about pre cum and I was on day 15 so I took an i-pill (ECP) after 7 hours. My period is due Feb 22. After taking i-pill I experienced cramp in my legs on feb 10 and today also. What are the chances of pregnancy? How to know i anything goes wrong? I am very worried.. help me.
