2. Basal Body Temperature Method
A woman’s body temperature drops by about half a centigrade before ovulation and rises again once the ovary releases the egg cell.
For the basal body temperature to work, the couple needs to track the woman’s basal body temp using a special thermometer at the same time each morning upon waking up and before getting out of bed.
To avoid unintended pregnancy, couples must abstain from the moment they see the drop to about 3 to 4 days after the woman’s temperature rises again.
3. Cervical Mucus Method or Billings Method
Another way on how to avoid pregnancy naturally is to inspect the woman’s cervical mucus.
According to experts, couples should refrain from sexual intercourse from the day the cervical mucus becomes thin, clear, and stretchy up to the 4th day after the mucus becomes thick, cloudy, and sticky.
For fertility awareness methods to work, couples need to be consistent in following the instructions correctly. Still, remember that other factors may come into play.
Case in point: illnesses, stress, and environment may affect the body temperature. Likewise, the calendar method won’t work if the woman has irregular menstruation. And finally, changes to cervical mucus are unique to every woman.
