Natural family planning methods help a couple avoid pregnancy without the aid of a birth control products such as IUDs or pills. Natural family planning methods help a woman determine when she is ovulating, which is when the ovary releases an egg ready for fertilization. A woman experiences various physical changes during ovulation, and by closely observing and recording those changes, a family can naturally manage birth control.
Ovulation Method
According to the FamilyDoctor website, the ovulation method or mucus method focuses on the consistency of a woman's cervical mucus. During ovulation, an increase of the estrogen hormones changes the appearance and feel of the mucus in the cervix. A woman can determine the days before and after ovulation by inserting her fingers into her vagina and checking the mucus in her cervix. She is likely to get pregnant if the mucus is clear and stretchy, similar to the texture of an uncooked egg.
Symptothermal Method
The symptothermal method requires a woman to chart her temperature every morning after at least six hours of sleep. During ovulation, a woman will note that her temperature rises about .9 degrees. In addition, the United States Conference of Catholic Bishops states that she should also check her cervical mucus as with the ovulation method. The hormonal fluctuations that occur during ovulation will also cause the cervix to open and feel softer to the touch. Additionally, a woman should watch for sensitivity in the breasts, groin or vulva swelling, and mild abdominal pain---all signs of ovulation.
Rhythm Method
The rhythm method requires a woman to keep track of her menstrual cycles on a calendar. Unlike other methods, she does not need to check cervical mucus or her body temperature. Because a woman typically ovulates 14 days prior to the start of her period, she can determine her ovulation date based on previous menstrual periods. This method works best for women who have regular cycles. It does not allow for period fluctuations or delays commonly caused by stress and dietary changes.
