Official church teaching: YOU MAY NEVER USE CONTRACEPTION TO REGULATE BIRTHS, end of story.
Their are soooo few cases where the health of the mother is in danger. Just think of it this way, is it ok to sin because you don’t want your body to get hurt??? NO WAY, it is never ok to sin.
God has his reasons for getting you pregnant, maybe he wants you to die a martyr.
Plus NFP is more effective than contraception, because how can you get pregnant when you don’t have sex??? that is a no brainer. We know when a woman ovulates, you can only get pregnant when a woman ovulates, if you don’t have sex on or around when she is ovulating…impossible to get prego.
Contraception on the other hand kills babies, it tricks the body into thinking it is pregnant and is not effective anyway.
