I posted before I was done, lol. I had Mirena for 4 years and didn't have issues with it other than hubby getting poked, that was fixed by going to see doc and having her cut the strings shorter. After I had it removed so we could TTC again it was a nightmare though, I didn't have a period for over a year and wasn't ovulating either. Took a little over two years for us to get pregnant, I'm going to get the nonhormone copper IUD after this baby.
You can still breastfeed on the pill, your doctor will prescribe you a "minipill" which doesn't have as much hormone in it so it shouldn't affect your milk supply. I was on it after both my kids and still exclusively breastfed them.
My sister in law tried iud and her husband at the time cut his wee wee on it.. ouch. And it also made her have break outs. But I have heard many good stories about them on here. I guess it all depends on the lady!
