A new VA study found that women's attitudes towards becoming pregnant also play a role in their contraceptive use. Women who don't plan on getting pregnant but are open to the idea may be less likely to use birth control. The study, which analyzed data from 858 women veterans, suggests that routine assessment is needed to help women ma...
