The Rhythm Method

Similarly to withdrawal, the rhythm method requires no outside chemical tablets or devices to work and also remains a fairly unreliable method of contraception. The idea is based around three key pieces of knowledge. Firstly, that a woman ovulates every fourteen days before menstruation begins. Secondly, that sperm can survive within a woman for three days. Finally, that an egg is fertilized within twenty four hours of being released from the ovaries.  The idea is simple. From the first day of her period, a woman can count back around fourteen days, thus identifying their specific period of ovulation. Once this period is identified, the woman can thus choose to either abstain from sex during this time or wear an additional form of contraception. A six month record of period dates, daily temperature readings and studying mucus discharge can help the efficiency of the method. The periods outside of this, are seen as less fertile and therefore carry less risk of pregnancy.
