I am extremely confused as to what is going on and was hoping to find some answers. I have always had normal periods, always same time each month with the same symptoms, however on a few weeks ago I had unprotected sex during my most vertile days of the month. I am a few days from starting my normal period and for the last 5 days I have been experiencing menstrual cramps which has never has happened before my normal period. Is there any way I could be pregnant, and if not can someone please give a answer to why
