I tend to get really bad side effects with Birth Control. I gave up until my doctor suggested this.
The first week or so I had cramps, but my body got used to the ring and now it's fine.
After it got stuck on my boyfriend, we joked that I should have a goldfish next to the bed as a "prize" if he gets the ring stuck!
I now take it out during intercourse, which doesn't change it's effectiveness. The hormones are already in your bloodstream.
Also, do not wash it with warm/hot water. It makes the birth control less effective.
If you tend to get alot of yeast infections, do not use this ring. My roommate had them every few weeks, and my doctor told me it will make any vaginal infections worse if you already tend get them.
