Mirena
"I chose Mirena because The Pill became too expensive to buy every month.  I was happy to find out my insurance paid for 100% of the costs!  I only cramped for about two weeks after, and those were very mild, but I don't have a history of cramps either.  I do not have a period anymore (which is great for saving $ on tampons!) although I do still have some symptoms of PMS each month.  The only downside I have to say about it is that because Mirena doesn't have the same hormones as The Pill, my acne isn't being regulated like it was before, but it's definitely not unmanageable."
