It is my understanding that the Catholic Church does not approve of any
type of birthcontrol whatsoever. Natural family planning that happens
naturally is ok but if you are mamipulating the body in any way
(increased nursings), or withdrawling prior to ejaculation, or
calculating ovulation, taking temps, etc. it is considered birht control
and the bottom line is birth control is birth control and it is not ok
with the catholic church.

This however does not mean that a great many catholics do not practice
birth control.

Also, the church only approves of the missionary position for sex.
