I've used oral birthcontrol tablet, Nuvaring, & most recently I had Mirena put in by my OB. Out of all those I have personally enjoyed the Mirena the most.
When I first tried Nuvaring (2 years ago) I had trouble with it staying in. After about a week of it falling out anytime I did anything, I decided to call my OB. I set up a appointment, went in to the office & my OB inserted it for me.
Not even a whole day later the ring slid out again. This time I knew it wasn't the way it was positioned. It turns out that I have a tilted uterus. which in turn has caused my cervix to be closer to the front of my pelvic bone (rather than tilted towards my tail bone). So, my experience was terrible, however, I believe if my uterus was not tilted and my cervix was in the correct position I would not have had the problems I did.
I hope you find this information helpful. :)
