Ortho Evra
"I've been looking for a decent birth control for years now -- and, honestly, I still am.  I've tried the pill, injections, the ring, and even tried 3 times to implant an IUD.  My top two worst experiences were with the IUD and the patch.  I've been on the patch for two months now...and the symptoms are horrible.  My hands, feet, and breasts have been swollen the whole time, and incredibly painful.  I've had both diarrhea and constipation, and non-stop bloating.  I took a whole week off work because of a migraine.  Usually I'm very level tempered, but since I started the patch I'm pissed off at everything.  I haven't been able to eat anything in days.  Not to mention, it keeps falling off after a few days."
