How effective are birth control pills without using a condom?
Although birth control pills may reduce the risk of your getting pregnant, they DO NOT protect you from contracting sexually transmitted infections or diseases such as HIV. Generally, the pill is 97 to 99% effective in preventing pregnancy, if used properly. Note that there are two main types of birth control pills; there are combination pills containing estrogen and progesterone, and there are are progesterone-only pills. It has been shown that the combination pills are somewhat more effective than the progresterone-only pills. Consistent and correct use of the combination pills results in only 1% of women becoming pregnant.
