The truth is, most women spend the majority of their lives trying not to get pregnant. According to the Guttmacher Institute, by the time a woman with two children is in her mid-40s she will have spent only five years trying to become pregnant, being pregnant, and not being at risk for getting pregnant following a birth. But to avoid getting pregnant before or after those two births, she would had had to refrain from sex or use contraception for an average of 25 years. Almost all American women (99 percent), ages 15-44, who have had sexual intercourse use some form of birth control.
