In all charity, the practice of any form of contraception, including NFP, is a mortal sin. You are thwarting God’s desire to give you children, which is an evil act.
Maybe this is what you are really sensing.
THIS IS NOT THE CHURCH TEACHING!
NFP IS ABSOLUTELY ACCEPTABLE AS BIRTH CONTROL IN OUR CHURCH!
IT IS NOT SIN AT ALL WHEN USED AS PRESCRIBED BY THE CHURCH!

What should a couple do if they have a good reason to avoid having a child?
A married couple can engage in marital intimacy during the naturally infertile times in a woman’s cycle, or after child-bearing years, without violating the meaning of marital intercourse in any way.
This is the principle behind natural family planning (NFP). Natural methods of family planning involve fertility education that enables couples to cooperate with the body as God designed it.
Is there really a difference between using contraception
and practicing Natural Family Planning?
On the surface, there may seem to be little difference. But the end result is not the only thing that matters, and the way we get to that result may make an enormous moral difference. Some ways respect God’s gifts to us while others do not. Couples who have practiced Natural Family Planning after using contraception have experienced a profound difference in the meaning of their sexual intimacy.
When couples use contraception, either physical or chemical, they suppress their fertility, asserting that they alone have ultimate control over this power to create a new human life. With NFP, spouses respect God’s design for life and love. They may choose to refrain from sexual union during the woman’s fertile time, doing nothing to destroy the love-giving or life-giving meaning that is present. This is the difference between choosing to falsify the full marital language of the body and choosing at certain times not to speak that language.
The Church’s
support for NFP is not based on its being “natural” as opposed to artificial. Rather, NFP respects the God-given power to love a new human life into being even when we are not actively seeking to exercise that power. However, because NFP does not change the human body in any way, or upset its balance with potentially harmful drugs or devices, people of other faiths or of no religious affiliation have also come to accept and use it from a desire to work in harmony with their bodies. They have also found that it leads couples to show greater attentiveness to and respect for each other.
