 In one study, they found that fewer than 20% of postpartum women initiated contraceptive use within 6 months of return of fecundity, and the percentage slowly increased to 34% by the 12th month.The methods of contraception used include injectables (40%), condoms (16%), traditional methods (16%), oral contraceptive pills (15%), female sterilization (10%), IUDs (3%) and implants (2%).Factors that increased the likelihood of contraceptive initiation after birth included women reporting autonomy in household decision making, use of contraception prior to pregnancy, ages 25–34 (compared to ages 15–24), and high wealth and education status.
