What brands of birth control have you tried that have given you the least amount of negative side effects? I have always had a lot of problems with my periods.  I have extremely painful cramps and lower abdominal pain (to the point where I often miss a couple of days of work). It is possible that I have endometriosis, but it hasn't been formally diagnosed. The doctors' solution is usually to take birth control.  I have tried several kinds but I always give up because I can't handle the side effects.  The most common side effects I get are:  mood swings, weight gain, and acne (breakouts).  I'm looking for suggestions on birth control pills to try from women with similar problems. I've tried Necon, LoEstrin, Orthro-Tri-Cyclin, Ortho Evra (the patch), the ring, and some others which I'm forgetting. Any advice would be much appreciated.
