I have only used the ring for one cycle and a few weeks in there were a few days of excruciating nausea and lower intestinal pain. Otherwise, just general discomfort a couple of times a week. I removed the ring last Friday and have been having continuous nausea and abdominal discomfort since last Thursday. No pain relievers that generally do the trick are working, not even my failsafe Midol. Besides being worrisome about my health, it's wearing having to put up with all of this. I've only been married for a few weeks and it's already putting a damper on things as I have no drive.
