"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&#039;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&#039;t have the same hormones as the pill, my acne isn&#039;t being regulated like it was before, but it&#039;s definitely not unmanageable."
