Pastor Stuckwisch did a blog post about contraception. Actually, there is a longer one, but this is the brief... and I like it very much. I would perhaps slightly quibble with 7... but only in the sense that their can be research done there... but I think he gives quite reasonable advice... especially if you or your bride is not a medical professional so you don't really *know* what the drugs in question do.
Other than that -- this is really, really good. Especially point 12.
12. The morality of contraception is not measured in the external action, nor in the particular method that is used vis-à-vis other methods of contraception, but it is measured in the heart.
