I am a scientist, by training and trade. If you want to post to me a "study" then you'll need to understand the difference between an opinion piece by non-scientists and an academic paper that is subject to peer review.

To your post, here is an academic article on the subject.

Women’s satisfaction with birth control: a population survey of physical and psychological effects of oral contraceptives, intrauterine devices, condoms, natural family planning, and sterilization among 1466 women

If you want to find scholarly articles, and not just pop-culture gibberish, use something like Google Scholar and find articles that have some level of academic rigor.

These are articles published in scientific publications, conform to academic rules, and are subject to peer review. They are void of commercialism, politics, unsubstantiated and unreferenced statements, and provide conclusions that also include additional further studies the paper did not include. They are fact-based and limit any opinions.

I have indeed looked into the latest scientific research on NFP. The stats are good. Try this:

Scientific research on NFP

WE can have a cordial discussion this point by point, if you wish. I'm here to learn.
