HI, I am 23 years old and had a first unprotected sex with my boy friend, after 1 week of periods, after a 2-3 hours, i had taken a I-pills which is an contraceptive medicine, then again I had protected sex with my boy friend within next 5-6 days and again I had periods in those days for 2-3 days. Now the time has been passed approximately 1 month and 4 days, but still I am not in my periods... so is that means that I am a pregnant???
