I am currently on Ocella (generic for Yasmin), I have been on it for almost a month, I start the inactive pills tomorrow night. Before I took Ocella, I was taking Yaz(and I switched immediatly). My last period lasted for 3-4 days. I should start my period on March 11th. Yesterday I had light pinkish/red blood when I wiped and some cramping and now I am having light brown discharge that is odorless. I have not missed any pills, and I do have unprotected sex. Could this be because I am just now in the first month of the new pills or could this mean I am pregnant???
