Well first let me first say this post is more about my sister then me! She is much older and married but heavily contracepting. Even though I'm much younger I still know the worth of not using contraceptives and have heard a lot about how great NFP can be for couples, but I didn't know how to respond to her when she told me that NFP (the rhythm method is what she called it) wouldn't work for her because she has always had irregular cycles and still does. I let the subject dropped but recently gave her a book on NFP so I'm wondering if she'll ask me about it again. How should I respond to this? I looked it up online and found a lot of secular sites saying that NFP just wont work if you have irregular cycles but I thought this probably couldn't be totally right because the church wouldn't stand behind it so much if it only worked on a certain amount of people.
Does anyone have any experience with this? I want to help my sister (i hate that she fills her body with such dangerous things as contraceptives but gives her dog organic dog food) but I feel so discouraged! Its so hard to talk to her about stuff like this with her being 12 years my senior and married and me being a teenage virgin! Its also made harder by the fact that shes left the church and is pretty anti catholic. If anyone could help or give advice on how to minister with her that would be great!
