Has anyone got one of these? I've just had my second baby and I think our family is probably complete. I've had a copper coil before and didn't have any real problems with that but it made my periods intolerably long so I felt I was bleeding most of the month. I'd prefer to avoid or limit hormones especially as I'm breastfeeding, and it seems this one has less in it than a Mirena. It would be good to know what this is like.
