Periodic abstinence is a natural method of contraception where the couples avoid or abstain from coitus during the period of the menstrual cycle when:

1. There is menstrual flow

2. The ovulation is most likely to occur

3. The corpus luteum is most active

4. The proliferative phase begins

Progesterone alone or in combination with estrogen can also be used as contraceptives by females as injections or implants under their skin. When used in this manner, they:

1. do not affect the release of the ovum

2. induce a foreign body reaction leading to rejection of the implanted blastocyst

3. can cause increased risk of ectopic pregnancy

4. have a much longer effective period

Emergency contraception is administering any of the following within 72 hours of unprotected sexual activity except:
1. Combination pill
2. IUD
