I am very regular until I started to have unprotected sex last dec 2012, i noticed last Feb 28 there was a spotting and my period was about to come by march 5 and it did come on the exact date, i have a 26 day cycle, and was suppose to get my period on march but it was late on march 30 and it came april 2. I test last april 8 it turned out faint positive, now i was suppose to have my period last april 28 but then I'm late for quite few days I started to bleed may 1 and it is very light only when I stand up and pee.
