My period started September 23 but I had light spotting a few days before.  I had sex October 2nd and had horrible cramps from the 8th until the 12 (feeling nacious on the 5th).  My period is due again on the 23 and have been cramping since the 16th on and off.  I have no other symptoms but a faint metallic taste in my mouth and cramps practically all month :(
