I have been on Desogen now for about 8 months. At first I started noticing that I would get terrible PMS which I had never experienced before with any other pill and I have used Yasmin, Alesse, and Orthotrycyclene. My side effects seem to change each month. At first it was extreme PMS before each cycle and now I get no PMS before my cycle, but during my 7 days off I get very little bleeding and then when I start back on the pill I get cramping with spotting and the PMS symptoms start and have been getting longer and longer each month. I hate this feeling of being out of control of my emotions. This month I had weepiness that is very rare for me. Each month is a new symptom. I just want to know what to expect every month.
