Some women stop ovulating when they have a Mirena coil fitted.

One benefit of Mirena is that you can basically forget about it after placement. If you have suffered from heavy periods in the past, or currently. The Mirena system was found to reduce heavy periods in most women. If you are not opposed to hormonal birth control, or have had bad experiences with it in the past.
