I began this bc after switching from Yasmin. My husband left for afghanistan for a year, during that year I was on this pill. At first I had mood swings and headaches but eventually that evened out. No weight gain but I did have a lot of breakouts. No break through bleeding or heavy periods. HOWEVER, after a year of taking this correctlly, on time, no drug interactions such as antibiotics or anything herbal-the first night my husband came back from afghanistan I got pregnant. Yasmin may have those lawsuits but that bc worked, this one did not.
