Contraception The "Safe Period"
****************** *****************
Rhythm Method Up to 85% effective
************* if used with care
This method attempts to predict the
time that a woman is most fertile and
intercourse should be avoided at this
time. The body temperature is measured
daily and the vaginal mucous checked.
Advantages
No risk. No mechanical devices. May
suit some with religious objections to
other methods.
Disadvantages
Not very reliable. Needs training &
restraint. Difficult for women with
irregular cycles and after childbirth.
