Hi, I am 25 years old and visited an old friend 2 weeks ago. There is a mutual physical attraction between the two of us and one thing led to another and we had unprotected sex. I had my period on February 11th and am now due any day now. I have not had any nausea or headaches or breast tenderness or soreness. I am having slight cramping today but nothing major and had slight lower back pain earlier this week. I know its too early to test but was wondering if there is a chance I could be pregnant. Can you have very slight cramping a few days before your period? Thanks/
