Need answers i'm confused. :( Is it somekinda pregnancy related bleeding or usual period?

[MissPhil]

I had my last period, last september 21-25 2011, heavy period. as usual, and i have regular period. It happens in every line of 2 in the calendar. i have never had sex since january, then when my boyfriend arrived, we had unprotected sex in the october 2nd, 5th, 7th, and without any signs of impending period. in the morning of 9th of october, i had this light period like bleeding, and i expect my period to have it on the next 20th something of october. and normally on my period, first day would be my heaviest day of bleeding, i can soak up to 2-3 pads. but this unusual thing is this frst day, is very light. still we continued having sex in the 11th of october, the characteristic of this period like bleeding is lighter than usual, it lasted for 3 days. i have cramping usually during my period. but i ddnt feel it this time. and now. after the so called period is gone. i'm now feeling sick.actually i'm sick. really, like i feel my body temps above the normal, colds, and cough. ugh! i'm very confused. is it a period? or decidual bleeding? somebody please answer
