Description
The mini-pill is a contraceptive pill that contains only progesterone (the other pills contain estrogen and progesterone).
Effectiveness
It is close to 99% effective if taken very regularly. This method is very effective, particularly for women over 40 years or women who are breastfeeding.
How it works
The mini-pill acts on the cervix by rendering the cervical mucus less permeable to sperm. It also acts by altering the lining of the uterus (endometrium), making it unsuitable for a fertilized ovum (egg). In a certain number of women, the mini-pill prevents ovulation.
Indications
The mini-pill is a good contraceptive choice for women who are breastfeeding or those who cannot take a pill containing estrogen.
Contraindications
All women may use the mini-pill except those who think they may be pregnant or who are experiencing vaginal bleeding of unknown origin.
Side effects
The main side effect associated with taking the mini-pill is irregular periods. About forty percent (40%) of women will have irregular periods , 40% of women will have regular periods and 20% will experience amenorrhea (absence of menstrual periods). Irregular periods are less likely to occur in women who are breastfeeding.
