How To Prevent Pregnancy Using Natural Methods?

There are different natural techniques that can help prevent pregnancy without the use of birth control. These methods are also referred to as behavioral methods,

  • Fertility awareness: It should be noted that pregnancy occurs only when the sexual intercourse takes place around the time of ovulation. Maintaining details of the menstrual cycle and estimating the day of ovulation can help prevent pregnancy. In normal menstrual cycle of 28 days, ovulation takes place around the 14th day, hence it is recommended to avoid sexual intercourse between the 10th to the 18th day of the menstrual cycle.
  • Studies have shown that the basal metabolic rate increases during ovulation. Maintain a record of basal metabolic rate during the menstrual cycle can help the female identify the day of ovulation and prevent pregnancy by avoiding sexual intercourse at this time.
  • Lactational amenorrhea: Sexual intercourse during lactation is also a natural way of preventing pregnancy. Prolactin released during lactation, prevents ovulation naturally. The lactational amenorrhea can last for about six to eight months after pregnancy, especially when the infant is on breast milk.
  • Total abstinence is another technique of preventing pregnancy. Not having sexual intercourse at all prevents the possibility of becoming pregnant.
