I had sex during my period,(while my period was flowing like the 3rd day or so, my period is usually 3to 5 days and its regular) unprotected, and 2 weeks later I'm seeing my period again? Could I be preganat? As in my period ended 29th/30th Nov, I noticed blood early this morning?it is not heavy like my period just spotting, if I am preganant, what drugs can I use to stop the pregnancy.
