I was on the pill Gianvi the generic brand of YAZ and the last 2 months I had spotting. The first month I spotted 2 weeks before my period and then got my period. The second month I spotted 3 weeks before my period I had spotting but then some days I had full on bleeding and then I had my period when I was supposed to get it. In the mean time I was with my boyfriend and we didn't use any other protection because I am on the pill. Also, recently I have been having white and sometimes clear discharge a lot, which I never really have. I have heard that I was spotting because my birth control stopped working? Is it possible that I can be pregnant?

Thank you,
S
