Progestin-only pills (POP). This type of pill contains no estrogen. Called the progestin-only pill, or "mini-pill," it's ideal for breastfeeding women because estrogen reduces milk production. It's also ideal for women who cannot take estrogen. Progestin-only pills primarily work by preventing ovulation, thinning the endometrium and thickening the cervical mucus, thereby preventing sperm from entering the uterus. However, with progestin-only birth control pills, ovulation isn't consistently suppressed, so the actions on cervical mucus and the endometrium are the critical factors. To work effectively, they must be taken at a certain time every 24 hours.
Advantage of POPs:
* decreased menstrual blood loss
* decreased menstrual cramps and pain
* can be used by breast-feeding women immediately after delivery
* an option for women who cannot use estrogen, such as those who are over 35 and still smoke
* easily reversible
Disadvantages:
* irregular bleeding patterns, spotting or breakthrough bleeding
* must be taken at the same time every day
* do not protect against sexually transmitted infections; women at risk must use condoms
* increased risk of follicular cysts
* may be slightly less effective than combination oral contraceptives
Possible side effects:
* amenorrhea (absence of a monthly period)
* irregular bleeding
* tender breasts
* nausea
* headaches
Ask yourself the following questions to determine if POPs are the right choice for you:
* Are you the type of person who can remember to take a pill at exactly the same time every day?
* Will irregular bleeding or spotting bother you or interfere with intimacy?
* Are you breastfeeding, but feel that you need contraception?
* If you are at risk for sexually transmitted infections, will you use condoms for protection?
* Do you need to avoid taking estrogen?
