Okay I have been on Yasmin for a year and 1/2 I think.....Anyway never had any problems with it at all. Last month I was 3 days later then normal and this month I started spoting before my last week has ended. I have 3 days left of my cycle. For the last year I have gotten my period on the tueday after I stop taking the actives....any reason why this is changing....nothing new except I was sick and on antibotics last month but not this one......
