There is another type of IUD called the Paraguard Copper.. it is a 10 year IUD instead of the five like the Mierena. It is non hormonal so as in no weight gain and no hormones being put into your body. You can ask your doctor about it and they can give you better information.
I love not having to remember to take it everyday like the pill, or switching out the patch or the ring every so often. Hope you find one you like!
