Re: The IUD Mirena...
I don't have Mirena myself, but from what I've read, some women using it have problems with milk supply and some don't. There's no way to know which camp you'll fall into without trying the thing out. There is, however, an alternative to Mirena which is not a barrier method: a non-hormonal IUD. I believe the brand name is Paragaurd.
