Joan, I repeat:  pregnancy is not a disease.  Of course there are conditions that are specific to pregnancy eclampsia, etc), and yes, there are unique risks during pregnancy.  That is why there are obstetricians.
But none of that is relevant to what I said:  pregnancy is not a disease, and we should not expect medical insurance to cover drugs or devices designed to avoid it.   
It’s customary in discussions like this to raise the spectre of women who are healthy enough to engage in sexual intercourse but otherwise so frail enough that pregnancy would be the death of them.  But we all know that the overwhelming majority of contraception in the western developed world is used because having a baby would be a major inconvenience.
If any organisation on this earth deserves to be denigrated, it is the Guttmacher Institute.  It is evil, pure and simple.
