I'm about to start this in 7 days. I am switching off of Desogen (taken for 10 years for endometriosis - though I was off for 2 years while conceiving and pregnant 3 years ago). I'm 41 and suspect peri-menopause (hard to tell when on BCPs). My CURRENT complaints are v. dryness, weight gain and low drive... I'm hoping the lower progesterone in Loestrin will help. Any one else had expereience going from Desogen to Loestrin?
